     DETAILED DESCRIPTION OF THE INVENTION 
     Some embodiments of the present disclosure will now be described more fully hereinafter with reference to the accompanying drawings, in which some, but not all embodiments of the disclosure are shown. Indeed, these disclosures may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. Like numbers refer to like elements throughout. 
     The phrases “in one embodiment,” “according to one embodiment,” “in some embodiments,” and the like generally mean that the particular feature, structure, or characteristic following the phrase may be included in at least one embodiment of the present disclosure, and may be included in more than one embodiment of the present disclosure (importantly, such phrases do not necessarily refer to the same embodiment). 
     The word “example” or “exemplary” is used herein to mean “serving as an example, instance, or illustration.” Any implementation described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other implementations. 
     If the specification states a component or feature “may,” “can,” “could,” “should,” “would,” “preferably,” “possibly,” “typically,” “optionally,” “for example,” “often,” or “might” (or other such language) be included or have a characteristic, that a specific component or feature is not required to be included or to have the characteristic. Such a component or feature may be optionally included in some embodiments, or it may be excluded. 
     As described above, RFID tags may be utilized to search, identify, and/or track objects, items, and people. In some examples, RFID tags may comprise an RFID inlay that includes an integrated circuit (IC) and an antenna that are disposed on a substrate. In some examples, the IC may include a memory circuitry that stores digital data (such as, but not limited to, an electronic product code (EPC), a unique tag identification (ID) number). For example, when an RFID tag is manufactured, a unique tag ID number may be encoded to the IC. When the RFID tag is attached to an object, the unique tag ID number can be associated with the object for searching and tracking purposes. 
     In some embodiments, the IC is connected to the antenna and may utilize the antenna to transmit digital data to an RFID reader via radio waves. In some examples, the RFID reader may convert the radio waves received from the RFID tag to digital data. For example, the RFID reader may generate a high frequency electromagnetic wave (also referred to as a radio frequency (RF) interrogation signal), which may trigger the RFID tag to transmit an RF response signal (which may embed digital data) to an RFID reader. In some embodiments, examples of RFID tags may be in the form of passive tags that are powered by energy from the RF interrogation signal transmitted by the RFID reader. In some embodiments, examples of RFID tags may be in the form of active tags that are powered by a battery. 
     In some embodiments, an RFID printer refers to an apparatus that can encode digital data (such as, but not limited to, the unique tag ID number) into an RFID inlay of an RFID tag. For example, the RFID printer may comprise an antenna that can transmit RF signals to the RFID inlay of an RFID tag to establish a data link between the antenna of the RFID printer and the RFID inlay of the RFID tag. In some examples, an RF signal is an electromagnetic wave that can transport information through air from one point to another. In some examples, digital data to be written to the RFID inlay of the RFID tag (such as, but not limited to, the unique tag ID number) may be embedded in the RF signals by the RFID printer. In some embodiments, upon receiving the RF signals from the antenna of the RFID printer, the IC in the RFID inlay of the RFID tag may store the digital data (such as, but not limited to, the unique tag ID number) in the memory circuitry. In some embodiments, the IC in the RFID inlay of the RFID tag may transmit an RF signal back to the antenna of the RFID printer to acknowledge the receipt of digital information (such as, but not limited to, the unique tag ID number) and/or to confirm that the digital information (such as, but not limited to, the unique tag ID number) has been encoded in the IC of the RFID inlay. 
     In some embodiments, an RFID printer may print images (such as, but not limited to, barcodes) on the RFID tag in addition to encoding the RFID inlay of the RFID tag. 
     As described above, there are many technical challenges, difficulties, and limitations in manufacturing RFID tags and labels. 
     For example, in RFID printers (such as, but not limited to, industrial RFID printers), an RFID antenna is positioned under an RFID tag to encode digital data to the RFID tag. The RFID antenna needs to ensure that the RFID printer maintains lasting stability in the communications with the RFID tags while printing and encoding the RFID tags, regardless of the types/categories of the RFID tags. As a practical matter, there are many different types and categories of RFID tags. 
     As an example, RFID tags may include, but not limited to, normal RFID tags and anti-metal RFID tags (also referred to as on-metal RFID tags). In this example, an anti-metal RFID tag may include a shielding layer at the bottom of the anti-metal RFID tag that may shield or block RF signals. Because the RFID antenna of the RFID printer is positioned under the RFID tag, the RFID antenna may encounter difficulties in reading data from and/or writing data to the anti-metal RFID tag due to the shielding layer. In contrast, a normal RFID tag may not include the shielding layer, and the RFID antenna of the RFID printer may more easily read data from and/or write data to the normal RFID tag even if it is positioned under the RFID tag. 
     In some examples, in order to be compatible with different types of RFID tags (such as, but not limited to, both normal RFID tags and anti-metal RFID tags described above), an example RFID printer may use two antennas (for example, one antenna positioned above the RFID tag and one antenna below the RFID tag). When the RFID printer is calibrated, the two antennas can separately be switched on to perform read-write calibration operations on an RFID tag before selecting an appropriate antenna from the two antennas for encoding the RFID tag. For example, the antenna on top of the RFID tag can be turned on while encoding an anti-metal tag so as to avoid the shielding layer, while the antenna under the RFID tag can be turned on while encoding a normal RFID tag. 
     However, it may be not practical to implement two RFID antennas in every RFID printer. For example, many RFID printers may have certain requirements for space and/or cost, and implementing two antennas in such RFID printers may not satisfy the space and/or cost requirements. As an example, some RFID printers may require a compact housing (for example, due to the environment that the RFID printer is implemented in), and therefore does not provide sufficient space for including two antennas within the housing of the RFID printers. As another example, some RFID printers may require a low cost for manufacturing, and utilizing two antennas may increase the cost for manufacturing and therefore cannot be implemented in these RFID printers. 
     In contrast, various embodiments of the present disclosure overcome the above-referenced technical challenges and difficulties, and provide various technical improvements and benefits. 
     For example, an example RFID printer in accordance with embodiments of the present disclosure may provide an RFID antenna component that uses a rotating mechanism, such as via a rotatable antenna bracket component. The rotatable antenna bracket component (along with the RFID antenna component) can be rotated to different positions according to the type of RFID tag that the RFID printer is encoding. For example, the rotatable antenna bracket component (along with the RFID antenna component) can be rotated to be positioned above the RFID tag. As another example, the rotatable antenna bracket component (along with the RFID antenna component) can be rotated to be positioned below the RFID tag. As another example, the rotatable antenna bracket component (along with the RFID antenna component) can be rotated to be at an angle to the RFID tag. 
     For example, by default, the rotatable antenna bracket component (along with the RFID antenna component) is rotated to be positioned under the RFID tag to encode the RFID tag. When the RFID antenna component is encoding an RFID tag such as an anti-metal tag, the rotatable antenna bracket component (along with the RFID antenna component) is rotated to be positioned above the RFID tag. 
     For example, various embodiments of the present disclosure may rotate the RFID antenna component to different positions through RFID printer calibration. In some embodiments, the RFID antenna component is fixed on the rotatable antenna bracket component. In some embodiments, the rotatable antenna bracket component and other components (such as a media support component or a media guide) are fixed by a damping structure, and the RFID antenna component can hover in two positions that include one position being above the RFID tag and another position being below the RFID tag. If one of the positions fails during the RFID tag printing and calibration, the rotatable antenna bracket component can be rotated to another position (for example, by using a screwdriver to rotate a slot on the rotatable antenna bracket component). In some embodiments, examples of the present disclosure may determine the best position of the rotatable antenna bracket component (along with the RFID antenna component) for encoding each type and/or category of RFID tags. 
     As such, various example embodiments of the present disclosure may overcome various technical challenges and difficulties, and may be compatible to encode different types of RFID tags (such as, but not limited to, normal RFID tags and anti-metal RFID tags described above) while satisfying the space and cost requirements of many RFID printers. For example, various embodiments of the present disclosure use only one antenna to encode two or more types of RFID tags to meet space requirements and save costs. An example RFID antenna component in accordance with various embodiments of the present disclosure may use a rotating mechanism. The example RFID antenna component can be rotated to different positions (from a 0-degree position to ±180-degree positions) according to the types of RFID tags. 
     Referring now to  FIG.  1 A  to  FIG.  1 C , an example RFID printer  100  in accordance with various embodiments of the present disclosure is illustrated. 
     In particular,  FIG.  1 A  illustrates an example perspective view of at least a portion of an example RFID printer  100  that includes a rotatable antenna bracket component  103  in accordance with various embodiments of the present disclosure. In the example shown in  FIG.  1 A , the rotatable antenna bracket component  103  is positioned above an RFID media.  FIG.  1 B  illustrates another example perspective view of at least a portion of the example RFID printer  100  as the rotatable antenna bracket component  103  rotates in accordance with various embodiments of the present disclosure.  FIG.  1 C  illustrates another example perspective view of at least a portion of the example RFID printer  100  as the rotatable antenna bracket component  103  completes the rotation shown in  FIG.  1 B  in accordance with various embodiments of the present disclosure. In the example shown in  FIG.  1 C , the rotatable antenna bracket component  103  is positioned under the RFID media. 
     Referring now to  FIG.  1 A , in accordance with various embodiments of the present disclosure, an example RFID printer  100  is provided. In the example shown in  FIG.  1 A , the example RFID printer  100  comprises an example RFID antenna component  101  and an example rotatable antenna bracket component  103 . 
     In some embodiments, the example RFID antenna component  101  may comprise materials that can transmit RF signals, such as, but not limited to, metal (such as, but not limited to, etched copper, aluminum), conductive ink, and/or the like. Additionally, or alternatively, in some embodiments, the example RFID antenna component  101  may comprise one or more additional and/or alternative materials. 
     In some embodiments, the example RFID antenna component  101  may comprise a suitable antenna structure for transmitting RF signals. For example, the example RFID antenna component  101  may be a one-turn antenna that may be in the shape of a single loop. As another example, the example RFID antenna component  101  may be a multi-turn antenna that may be in the shape of a multi-turn loop. 
     While the description above describes some example structures of the RFID antenna component, it is noted that the scope of the present disclosure is not limited to the description and examples above. In some examples, an example RFID antenna component may include one or more additional and/or alternative structures. 
     In some embodiments, the example RFID antenna component  101  may convert electrical current into electromagnetic waves that are then radiated into space as RF signals. In some embodiments, the example RFID antenna component  101  may embed digital information in the RF signals (such as, but not limited to, the unique tag ID number). In some embodiments, the example RFID antenna component  101  may transmit the RF signals at one or more particular frequency bands and/or ranges. In some embodiments, the frequency bands and/or ranges of the RF signals may be determined based on the frequency bands and/or ranges of the RFID tag to be encoded by the example RFID printer  100 . 
     For example, the RFID tag to be encoded by the example RFID printer  100  may be an example ultra-high frequency (UHF) tag. The example UHF tag may operate at a 860 MHz to 960 MHz range if it is a passive tag, and may operate at 433 MHz if it is an active tag. In such an example, the example RFID antenna component  101  may emit RF signals at the 860 MHz to 960 MHz range for encoding a passive UHF tag, and may emit RF signals at 433 MHz for encoding an active tag. 
     As another example, the RFID tag to be encoded by the example RFID printer  100  may be an example high frequency (HF) tag, which may operate at 13.56 MHz. In such an example, the example RFID antenna component  101  may emit RF signals at 13.56 MHz for encoding an example HF tag. 
     As another example, the RFID tag to be encoded by the example RFID printer  100  may be an example low frequency (LF) tag, which may operate at a 125 KHz to 134.2 KHz range. In such an example, the example RFID antenna component  101  may emit RF signals at the 125 KHz to 134.2 KHz range for encoding an example LF tag. 
     While the description above describes some example frequencies and example frequency ranges for the example RFID antenna component to transmit RF signals, it is noted that the scope of the present disclosure is not limited to the description and examples above. In some examples, examples of RF signals generated and/or transmitted by the example RFID antenna component may be at or within one or more additional and/or alternative frequencies and/or frequency ranges. 
     Referring back to  FIG.  1 A , in some embodiments, the example rotatable antenna bracket component  103  comprises a first knob portion  105 , a first elongated portion  107 , and a first side portion  109 . 
     In some embodiments, the example rotatable antenna bracket component  103  may comprise materials such as, but not limited to, plastic. In some embodiments, the example rotatable antenna bracket component  103  may comprise one or more additional and/or alternative materials. 
     In some embodiments, the first elongated portion  107  may be in a shape similar to a cuboid shape. For example, the first elongated portion  107  may have a length that is elongated compared to its width and/or its height. In some embodiments, the print direction of the RFID media is in a parallel arrangement with a direction of the width of the first elongated portion  107 , details of which are described herein. 
     In some embodiments, the example RFID antenna component  101  is secured in the first elongated portion  107  of the example rotatable antenna bracket component  103 . For example, the first elongated portion  107  of the example rotatable antenna bracket component  103  comprises a first elongated surface  137  (as shown in  FIG.  1 A  and  FIG.  1 B ) and a second elongated surface  139  (as shown in  FIG.  1 C ). In some embodiments, the second elongated surface  139  of the first elongated portion  107  is opposite to the first elongated surface  137  of the first elongated portion  107 . In some embodiments, the example RFID antenna component  101  is secured on the first elongated surface  137  of the first elongated portion  107  (as shown in  FIG.  1 A  and  FIG.  1 B ). 
     In some embodiments, the example RFID antenna component  101  is attached to the first elongated surface  137  of the first elongated portion  107 . Additionally, or alternatively, the example RFID antenna component  101  is embedded in or on the first elongated surface  137  of the first elongated portion  107 . Additionally, or alternatively, the example RFID antenna component  101  is secured in the first elongated portion  107  of the example rotatable antenna bracket component  103  through one or more additional or alternative ways. 
     Referring back to  FIG.  1 A , in some embodiments, the first side portion  109  of the example rotatable antenna bracket component  103  projects from a first end  111  of the first elongated portion  107 . For example, the first side portion  109  may extend outwards from a surface of the first elongated portion  107  at the first end  111 . 
     In some embodiments, the first side portion  109  of the example rotatable antenna bracket component  103  is in a first perpendicular arrangement with the first elongated portion  107  of the example rotatable antenna bracket component  103 . For example, an outer surface of the first side portion  109  may be perpendicular to an outer surface of the first elongated portion  107 . 
     While the description above provides an example arrangement between the first side portion  109  and the first elongated portion  107 , it is noted that the scope of the present disclosure is not limited to the description above. 
     In some embodiments, the first side portion  109  of the example rotatable antenna bracket component  103  connects the first elongated portion  107  to the first knob portion  105 . As described above, the first side portion  109  may extend from an outer surface of the first elongated portion  107 . For example, the first side portion  109  may comprise a first surface and a second surface opposite to the first surface. The first surface of the first side portion  109  may have a first end, and the second surface of the first side portion  109  may have a second end that is opposite to the first end of the first surface of the first side portion  109 .

     In some embodiments, the first knob portion  105  may be in a shape similar to a cylinder shape. For example, the first knob portion  105  may comprise two parallel circular base surfaces that are joined by a curved side surface. In some embodiments, the curved side surface of the first knob portion  105  enables the first knob portion  105  (along with other portions of the example rotatable antenna bracket component  103 ) to be rotated. In some embodiments, a slot may be formed on one of the two parallel circular base surfaces, and the slot may be used to control the rotary position of the first knob portion  105  (along with other portions of the example rotatable antenna bracket component  103 ). 
     For example, the head of a flathead screwdriver may be inserted into the slot of the first knob portion  105 . As the flathead screwdriver rotates, the first knob portion  105  may rotate, causing the other portions of the example rotatable antenna bracket component  103  (including the first elongated portion  107  and the first side portion  109 ) to rotate. Additionally, or alternatively, the first knob portion  105  may be connected to one or more actuators or motors via one or more belts, and the one or more actuators or motors may control the rotary position of the first knob portion  105 . Additionally, or alternatively, the rotary position of the first knob portion  105  may be controlled through other mechanisms. 
     While the description above provides an example shape of the first knob portion  105 , it is noted that the scope of the present disclosure is not limited to the description above. In some examples, an example first knob portion  105  may be in one or more additional and/or alternative shapes. 
     In some embodiments, the example RFID printer  100  further comprises a printer housing  113 . In some embodiments, the printer housing  113  may provide an enclosure or case for some or all components within the printer housing  113 . In  FIG.  1 A , only a portion of the printer housing  113  is shown. 
     In some embodiments, the printer housing  113  comprises a first wall  115 . In some embodiments, the first wall  115  defines (e.g. includes) a first knob aperture  117 . In some embodiments, the first knob portion  105  of the example rotatable antenna bracket component  103  is positioned within the first knob aperture  117  of the printer housing  113 . For example, a diameter of the first knob aperture  117  may equal or be larger than a diameter of the circular base surface of the first knob portion  105  so that the first knob portion  105  is disposed within the first knob aperture  117  (e.g. the side surface of the first knob portion  105  being in contact with the first knob aperture  117 ). 
     In some embodiments, the first knob portion  105  of the example rotatable antenna bracket component  103  is rotatable within the first knob aperture  117  of the printer housing  113 . In some embodiments, the first knob portion  105  (and first side portion  109 ) of the example rotatable antenna bracket component  103  may provide a damping structure that connects the example rotatable antenna bracket component  103  to the printer housing  113 , while allowing the example rotatable antenna bracket component  103  to rotate. Because the example RFID antenna component  101  is secured in the first elongated portion  107  of the example rotatable antenna bracket component  103 , the example RFID antenna component  101  is rotated when the first knob portion  105  rotates within the first knob aperture  117  of the printer housing  113 . 
     In the example shown in  FIG.  1 A , the first knob portion  105  may define a knob portion axis  141 . For example, the first knob portion  105  may rotate along the knob portion axis  141 , which may be a central axis of the first knob portion  105 . In some embodiments, the example RFID antenna component  101  may define an RFID antenna axis  143 , which may be a central axis of the example RFID antenna component  101 . In some embodiments, at least because of the first side portion  109 , the knob portion axis  141  is parallel to the RFID antenna axis  143  and does not overlap with the RFID antenna axis  143 . In some embodiments, at least because of the first side portion  109 , the knob portion axis  141  may intersect the RFID antenna axis  143  but does not overlap with the RFID antenna axis  143 . As such, as the first knob portion  105  rotates along the knob portion axis  141 , the RFID antenna axis  143  of the example RFID antenna component  101  rotates around the knob portion axis  141  but does not overlap with the knob portion axis  141 . 
     Referring now to  FIG.  1 C , in some embodiments, the example rotatable antenna bracket component  103  further comprises a second knob portion  119  and a second side portion  121 . 
     In some embodiments, the second side portion  121  of the example rotatable antenna bracket component  103  projects from a second end  123  of the first elongated portion  107  of the example rotatable antenna bracket component  103 . For example, the second side portion  121  may extend outwards from a surface of the first elongated portion  107  at the second end  123 . In some embodiments, the second end  123  of the first elongated portion  107  is opposite to the first end  111  of the first elongated portion  107 . In some embodiments, the second side portion  121  of the example rotatable antenna bracket component  103  is in a second perpendicular arrangement with the first elongated portion  107  of the example rotatable antenna bracket component  103 , similar to those described above in connection with the first side portion  109 . 
     In some embodiments, the second side portion  121  of the example rotatable antenna bracket component  103  connects the first elongated portion  107  of the example rotatable antenna bracket component  103  to the second knob portion  119  of the example rotatable antenna bracket component  103 . For example, as described above, the second side portion  121  may extend from an outer surface of the first elongated portion  107 . 
     In some embodiments, the second side portion  121  may comprise a first surface and a second surface opposite to the first surface. The first surface of the second side portion  121  may have a first end, and the second surface of the second side portion  121  may have a second end that is opposite to the first end of the first surface of the second side portion  121 . In some embodiments, the second end  123  of the first elongated portion  107  is connected to the first end of the first surface of the second side portion  121 , and the second knob portion  119  is connected to the second end of the second surface of the second side portion  121 . 
     As shown in  FIG.  1 C , the second knob portion  119  may be in a cylinder shape, similar to the first knob portion  105  described above. In some embodiments, the second knob portion  119  is rotatable, similar to the first knob portion  105  described above. 
     In some embodiments, the example RFID printer  100  further comprises a first media support component  125 . In some embodiments, the first media support component  125  comprises a first media support surface  127 . In some embodiments, an RFID media may travel on the first media support surface  127 . In the example shown in  FIG.  1 C , the first media support component  125  may comprise a plurality of grooves for guiding the travel of the RFID media. 
     In the present disclosure, the term “RFID media” refers to a media that includes an RFID inlay. As described, the RFID inlay may include an IC and an antenna that are connected to one another and may be disposed on a substrate. In some embodiments, the example RFID printer may encode digital data to the IC of the RFID media through the example RFID antenna component. For example, an example RFID media may be in the form of an example RFID tag, an example RFID label, and/or the like. 
     In some embodiments, the first media support component  125  is positioned adjacent to the example rotatable antenna bracket component  103 . In some embodiments, an example RFID media travels on the first media support surface  127  in a printing direction. For example, the printing direction may be from the first media support component  125  to the example rotatable antenna bracket component  103 . 
     In some embodiments, the example RFID printer  100  further comprises a second media support component  129 . In some embodiments, the second media support component  129  comprises a second media support surface  131 . In some embodiments, an RFID media may travel on the second media support surface  131  in a printing direction. For example, the printing direction may be from the example rotatable antenna bracket component  103  to the second media support surface  131 . In the example shown in  FIG.  1 C , the second media support component  129  may comprise a plurality of grooves for guiding the travel of the RFID media, similar to those of the first media support component  125 . 
     In some embodiments, the second media support component  129  is connected to the first media support component  125  via a connection bridge component  133 . For example, the connection bridge component  133  may connect one end of the first media support component  125  to one end of the second media support component  129 . In some embodiments, the plurality of grooves on the first media support surface  127  are parallel to the plurality of grooves on the second media support surface  131  so as to continuously guide the travel of the RFID media. 
     In the example shown in  FIG.  1 C , the connection bridge component  133  creates a gap between the first media support component  125  and the second media support component  129 , and the example rotatable antenna bracket component  103  is positioned between the first media support component  125  and the second media support component  129 . 
     In some embodiments, the connection bridge component  133  defines (e.g. includes) a second knob aperture  135 . In some embodiments, the second knob portion  119  of the example rotatable antenna bracket component  103  is positioned within the second knob aperture  135  of the connection bridge component  133 . 
     For example, a diameter of the second knob aperture  135  may equal or be larger than a diameter of the circular base surface of the second knob portion  119  so that the second knob portion  119  is disposed within the second knob aperture  135  (e.g. the side surface of the second knob portion  119  being in contact with the second knob aperture  135 ). In some embodiments, the second knob portion  119  of the example rotatable antenna bracket component  103  is rotatable within the second knob aperture  135  of the connection bridge component  133 , similar to those described above in connection with the first knob portion  105  and the first knob aperture  117 . 
     In some embodiments, the travel of the RFID media may be driven at least in part by the roller  145 . For example, the RFID media may be a part of an RFID media roll that is placed on a media supply spindle within the example RFID printer  100 . In some embodiments, the RFID media is unwound from the RFID media roll and travels in a printing direction that includes to the first media support component  125 , then to the example rotatable antenna bracket component  103 , then to the second media support component  129 , and then to the roller  145 . In some embodiments, the roller  145  (and another roller that is placed on top of the roller  145 ) may rotate, which causes the RFID media to be unwound from the RFID media roll and travel in the printing direction as described above. 
     While the description above provides an example of printing direction, it is noted that the scope of the present disclosure is not limited to the description above. In some examples, an example printing direction may be different than those described above. For example, the roller  145  may be placed prior to the first media support component  125  in the printing direction. 
     In some embodiments, the first knob portion  105  and/or the second knob portion  119  are configured to provide a plurality of rotary positions. For example, the first knob portion  105  and/or the second knob portion  119  may be rotated manually and/or through one or more actuators/motors as described above. 
     In some embodiments, as the first knob portion  105  and/or the second knob portion  119  of the example rotatable antenna bracket component  103  rotate, the first elongated portion  107  (along with the example RFID antenna component  101 ) rotates as well. As such, the example rotatable antenna bracket component  103  is configured to provide a plurality of example RFID encoding configurations for the example RFID antenna component  101  based on the plurality of rotary positions of the first knob portion  105  and/or the second knob portion  119 . 
     For example, the plurality of example RFID encoding configurations comprises a first example RFID encoding configuration and a second example RFID encoding configuration. 
     In some embodiments, when the example rotatable antenna bracket component  103  is in the first example RFID encoding configuration, an example RFID media is above the example RFID antenna component  101 . 
     Referring now to  FIG.  1 C , an example of the first example RFID encoding configuration is illustrated. In this example, when the example rotatable antenna bracket component  103  is in the first example RFID encoding configuration, the example RFID media is above the second elongated surface  139  of the first elongated portion  107 . For example, the RFID media travels on the first media support surface  127  of the first media support component  125 , then on the second elongated surface  139  of the first elongated portion  107 , and then on the second media support surface  131  of the second media support component  129 . As shown, when the example rotatable antenna bracket component  103  is in the first example RFID encoding configuration, the example RFID antenna component  101  may encode the RFID media from the bottom of the RFID media. In some embodiments, the first example RFID encoding configuration may be implemented to encode digital data to an RFID media that does not include a shielding layer at the bottom of the RFID media (e.g. not an anti-metal RFID tag). 
     In some embodiments, when the example rotatable antenna bracket component  103  is in the second example RFID encoding configuration, the example RFID media is below the example RFID antenna component  101 . 
     Referring now to  FIG.  1 A , an example of the second example RFID encoding configuration is illustrated. In this example, when the example rotatable antenna bracket component  103  is in the second example RFID encoding configuration, the example RFID media is below the second elongated surface  139  of the first elongated portion  107 . 
     For example, the RFID media travels on the first media support surface  127  of the first media support component  125 , then under the second elongated surface  139  of the first elongated portion  107  (for example, above the gap between the first media support component  125  and the second media support component  129 ), and then on the second media support surface  131  of the second media support component  129 . As shown, when the example rotatable antenna bracket component  103  is in the second example RFID encoding configuration, the example RFID antenna component  101  may encode the RFID media from the top of the RFID media. In some embodiments, the second example RFID encoding configuration may be implemented to encode digital data to an RFID media that includes a shielding layer at the bottom of the RFID media (e.g. an anti-metal RFID tag). 
     As described above, in some embodiments, the first knob portion of the example rotatable antenna bracket component defines a knob portion axis, and the example RFID antenna component defines an RFID antenna axis. In some embodiments, the RFID antenna axis and the knob portion axis define an encoding direction for the example RFID antenna component to encode the example RFID media. In some embodiments, each of the plurality of example RFID encoding configurations is associated with a corresponding antenna angle that is between a printing direction of the example RFID media and the encoding direction. 
     Referring now to  FIG.  2 A  to  FIG.  2 D , example diagrams illustrating example antenna angles associated with example RFID encoding configurations in accordance with various embodiments of the present disclosure are illustrated.  FIG.  2 A  to  FIG.  2 D  illustrate example side views of an example rotatable antenna bracket component as the RFID media is positioned either above the example rotatable antenna bracket component or below the example rotatable antenna bracket component for encoding. 
       FIG.  2 A  and  FIG.  2 B  illustrate example antenna angles associated with the first example RFID encoding configuration. As described above, when the example rotatable antenna bracket component is in the first example RFID encoding configuration, an example RFID media is above the example RFID antenna component. 
     In some embodiments, when the example rotatable antenna bracket component is in the first example RFID encoding configuration, a first antenna angle associated with the first example RFID encoding configuration is within a first open interval between 0° to 180°. 
     For example, in the example shown in  FIG.  2 A , the RFID media may travel in a travel direction  206 A, and the example rotatable antenna bracket component  210 A is in the first example RFID encoding configuration so that the RFID media travels above the example RFID antenna component  212 A. When the RFID media is above the example RFID antenna component  212 A, the example RFID antenna component  212 A may transmit RF signals to encode the RFID media. In particular, the encoding direction  208 A may be defined by connecting the RFID antenna axis  204 A of the example RFID antenna component  212 A to the knob portion axis  202 A of the first knob portion  214 A of the example rotatable antenna bracket component  210 A. In the example shown in  FIG.  2 A , the antenna angle A may be 90°. In some embodiments, the example RFID antenna component  212 A may be in a parallel arrangement with the RFID media. 
     As another example, in the example shown in  FIG.  2 B , the RFID media may travel in a travel direction  206 B, and the example rotatable antenna bracket component  210 B is in the first example RFID encoding configuration so that the RFID media travels above the example RFID antenna component  212 B. When the RFID media is above the example RFID antenna component  212 B, the example RFID antenna component  212 B may transmit RF signals to encode the RFID media. In particular, the encoding direction  208 B may be defined by connecting the RFID antenna axis  204 B of the example RFID antenna component  212 B to the knob portion axis  202 B of the first knob portion  214 B of the example rotatable antenna bracket component  210 B. In the example shown in  FIG.  2 B , the antenna angle B may be a positive obtuse angle. 
     While the description above provides examples of antenna angles when the example rotatable antenna bracket component is in the first example RFID encoding configuration, it is noted that the scope of the present disclosure is not limited to the description above. In some examples, an example antenna angle when the example rotatable antenna bracket component is in the first example RFID encoding configuration may be of other values. For example, the example antenna angle when the example rotatable antenna bracket component is in the first example RFID encoding configuration may be a positive acute angle. 
       FIG.  2 C  and  FIG.  2 D  illustrate example antenna angles associated with the second example RFID encoding configuration. As described above, when the example rotatable antenna bracket component is in the second example RFID encoding configuration, the example RFID media is below the example RFID antenna component. 
     In some embodiments, when the example rotatable antenna bracket component is in the second example RFID encoding configuration, a second antenna angle associated with the second example RFID encoding configuration is within a second open interval between 0° to −180°. 
     For example, in the example shown in  FIG.  2 C , the RFID media may travel in a travel direction  206 C, and the example rotatable antenna bracket component  210 C is in the second example RFID encoding configuration so that the RFID media travels below the example RFID antenna component  212 C. When the RFID media is below the example RFID antenna component  212 C, the example RFID antenna component  212 C may transmit RF signals to encode the RFID media. In particular, the encoding direction  208 C may be defined by connecting the RFID antenna axis  204 C of the example RFID antenna component  212 C to the knob portion axis  202 C of the first knob portion  214 C of the example rotatable antenna bracket component  210 C. In the example shown in  FIG.  2 C , the antenna angle C may be −90°. In some embodiments, the example RFID antenna component  212 C may be in a parallel arrangement with the RFID media. 
     As another example, in the example shown in  FIG.  2 D , the RFID media may travel in a travel direction  206 D, and the example rotatable antenna bracket component  210 D is in the second example RFID encoding configuration so that the RFID media travels below the example RFID antenna component  212 D. When the RFID media is below the example RFID antenna component  212 D, the example RFID antenna component  212 D may transmit RF signals to encode the RFID media. In particular, the encoding direction  208 D may be defined by connecting the RFID antenna axis  204 D of the example RFID antenna component  212 D to the knob portion axis  202 D of the first knob portion  214 D of the example rotatable antenna bracket component  210 D. In the example shown in  FIG.  2 D , the antenna angle D may be a negative acute angle. 
     While the description above provides examples of antenna angles when the example rotatable antenna bracket component is in the second example RFID encoding configuration, it is noted that the scope of the present disclosure is not limited to the description above. In some examples, an example antenna angle when the example rotatable antenna bracket component is in the second example RFID encoding configuration may be of other values. For example, the example antenna angle when the example rotatable antenna bracket component is in the second example RFID encoding configuration may be a negative obtuse angle. 
     Referring now to  FIG.  3 A  to  FIG.  3 E , an example RFID printer  300  in accordance with various embodiments of the present disclosure is illustrated. 
     In particular,  FIG.  3 A  illustrates an example perspective view of a first media support component  325 , an example rotatable antenna bracket component  303 , and a second media support component  329  of the example RFID printer  300  in accordance with various embodiments of the present disclosure.  FIG.  3 B  illustrates an example perspective view of at least a portion of the example RFID printer  300  in accordance with various embodiments of the present disclosure.

In some embodiments, the second elongated portion  345  of the example rotatable antenna bracket component  303  is devoid of any RFID antenna component. For example, there is no RFID antenna component in the second elongated portion  345  because the rotatable antenna bracket component  303  can rotate the example RFID antenna component  301  to different positions. 
     In some embodiments, the first elongated portion  307  and the second elongated portion  345  are in a parallel arrangement with one another. For example, the example rotatable antenna bracket component  303  comprises a first side portion  309  that connects a first end  311  of the first elongated portion  307  and a first end  347  of the second elongated portion  345 . In some embodiments, the first side portion  309  of the example rotatable antenna bracket component  303  is in a first perpendicular arrangement with the first elongated portion  307  of the example rotatable antenna bracket component  303 . For example, an outer surface of the first side portion  309  may be perpendicular to an outer surface of the first elongated portion  307 . In some embodiments, the first side portion  309  of the example rotatable antenna bracket component  303  is in a second perpendicular arrangement with the second elongated portion  345  of the example rotatable antenna bracket component  303 . For example, an outer surface of the first side portion  309  may be perpendicular to an outer surface of the second elongated portion  345 . 
     In some embodiments, the example rotatable antenna bracket component  303  comprises a first knob portion  305 . In some embodiments, the first knob portion  305  may comprise two half-cylinder shape protrusions and may define a gap between the two half-cylinder shape protrusions. The gap may be used to control the rotary position of the first knob portion  305 . For example, the head of a flathead screwdriver may be inserted into the gap between the two half-cylinder shape protrusions to rotate the first knob portion  305 . Additionally, or alternatively, the first knob portion  305  may be connected to one or more actuators or motors via one or more belts, and the one or more actuators or motors may control the rotary position of the first knob portion  305 . 
     In some embodiments, the first knob portion  305  is disposed on an outer surface of the first side portion  309  of the example rotatable antenna bracket component  303 . For example, the first knob portion  305  may protrude from a side surface of the first side portion  309 . As such, the first side portion  309  connects a first end  311  of the first elongated portion  307  to the first knob portion  305  of the example rotatable antenna bracket component  303 , and connects a first end  347  of the second elongated portion  345  to the first knob portion  305  of the example rotatable antenna bracket component  303 . 
     Referring now to  FIG.  3 B , the example RFID printer  300  further comprises a printer housing  313 . In some embodiments, the printer housing  313  may provide an enclosure or case for some or all components within the printer housing  313 . In the example shown in  FIG.  3 B , only a portion of the printer housing  313  is shown. 
     In some embodiments, the printer housing  313  comprises a first wall  315 . In some embodiments, the first wall  315  defines (e.g. includes) a first knob aperture  317 . In some embodiments, the first knob portion  305  of the example rotatable antenna bracket component  303  is positioned within the first knob aperture  317  of the printer housing  313 . For example, a diameter of the first knob aperture  317  may equal or be larger than a diameter of the first knob portion  305  so that the first knob portion  305  is disposed within the first knob aperture  317 . In some embodiments, the first knob portion  305  is rotatable within the first knob aperture  317 . 
     In some embodiments, similar to those described above in connection with  FIG.  1 A  to  FIG.  1 C , the example rotatable antenna bracket component  303  comprises a second side portion and a second knob portion. 
     For example, the second side portion of the example rotatable antenna bracket component  303  connects a second end of the first elongated portion  307  and a second end of the second elongated portion  345 . In some embodiments, the second end of the first elongated portion  307  is opposite to the first end  311  of the first elongated portion  307 . In some embodiments, the second end of the second elongated portion  345  is opposite to the first end  347  of the second elongated portion  345 . In some embodiments, the second side portion of the example rotatable antenna bracket component  303  is in a first perpendicular arrangement with the first elongated portion  307 , and is in a second perpendicular arrangement with the second elongated portion  345 . 
     In some embodiments, the second knob portion is shaped and/or positioned similar to those of the first knob portion  305  described above.

In some embodiments, the second side portion connects the second end of the second elongated portion  345  to the second knob portion of the example rotatable antenna bracket component  303 . 
     In the examples shown in  FIG.  3 A  and  FIG.  3 B , the example RFID printer  300  further comprises a first media support component  325 , similar to the first media support component  125  described above in connection with at least  FIG.  1 A  to  FIG.  1 C .

     Referring now to  FIG.  5   , an example method  500  is illustrated. In particular, the example method  500  illustrates example steps/operations of calibrating an RFID printer by determining the best RFID encoding configuration for encoding a type of the RFID media in accordance with various embodiments of the present disclosure. For example, the example method  500  may include determining a type of the RFID media for calibration, causing an example rotatable antenna bracket component to rotate according to a plurality of example RFID encoding configurations, causing the example RFID printer to determine a signal strength for encoding the RFID media at each of the plurality of example RFID encoding configurations, and determining the best RFID encoding configuration for encoding the type of the RFID media based on the signal strength. 
     Referring now to  FIG.  5   , the example method  500  starts at step/operation  501 . In some embodiments, subsequent to and/or in response to step/operation  501 , the example method  500  proceeds to step/operation  503 . At step/operation  503 , a processing circuitry (such as, but not limited to, the processing circuitry  402  of the RFID printer  400  described in connection with  FIG.  4    above) may determine a type of the RFID media for calibration. 
     For example, when an example RFID printer receives an RFID media, the RFID antenna component may initiate read operations (such as, but not limited to, by transmitting RF signals, similar to those described above) to interrogate the RFID media, and the RFID media may transmit RF signals back to the RFID antenna component that indicate a type of the RFID media. 
     Additionally, or alternatively, the example RFID printer may receive an indication of the type of the RFID media. For example, the example RFID printer may receive an indication in the form of a user input that indicates the type of RFID media. Additionally, or alternatively, the example RFID printer may determine the type of the RFID media through other ways. 
     As described above, example types of the RFID media include, but are not limited to, anti-metal tags, normal tags, and/or the like. 
     Referring back to  FIG.  5   , subsequent to step/operation  503 , the example method  500  proceeds to step/operation  505 . At step/operation  505 , the processing circuitry (such as, but not limited to, the processing circuitry  402  of the RFID printer  400  described in connection with  FIG.  4    above) may cause an example rotatable antenna bracket component to rotate according to a plurality of example RFID encoding configurations. 
     In some embodiments, the processing circuitry may transmit instructions to one or more actuators and/or motors that are connected to a knob portion of the example rotatable antenna bracket component, and the one or more actuators and/or motors may cause the knob portion of the example rotatable antenna bracket component to rotate upon receiving the instructions. Additionally, or alternatively, the processing circuitry may cause instructions to rotate the knob portion to be rendered on a user interface (for example, a display on the RFID printer), and a user may rotate the knob portion based on the instructions. 
     As described above, each of the plurality of example RFID encoding configurations may be associated with a corresponding antenna angle, and the example antenna component may encode the RFID media at different antenna angles. For example, in one RFID encoding configuration, the example antenna component may encode the RFID media from the top of the RFID media; in another encoding configuration, the example antenna component may encode the RFID media from the bottom of the RFID media, similar to those described above. 
     Referring back to  FIG.  5   , subsequent to step/operation  505 , the example method  500  proceeds to step/operation  507 . At step/operation  507 , the processing circuitry (such as, but not limited to, the processing circuitry  402  of the RFID printer  400  described in connection with  FIG.  4    above) may cause the example RFID printer to determine a signal strength for encoding the RFID media at each of the plurality of example RFID encoding configurations. 
     For example, when the example antenna component encodes the RFID media at an antenna angle, the example antenna component may transmit an RF signal to the RFID media, and receive an RF signal from the RFID media in response. In some embodiments, the processing circuitry may determine a signal strength (for example, based on the amplitude of the RF signal) associated with the antenna angle. In some embodiments, if the example antenna component does not receive any RF signal in response, the processing circuitry may determine a signal strength associated with the antenna angle to be zero. 
     Referring back to  FIG.  5   , subsequent to step/operation  507 , the example method  500  proceeds to step/operation  509 . At step/operation  509 , the processing circuitry (such as, but not limited to, the processing circuitry  402  of the RFID printer  400  described in connection with  FIG.  4    above) may determine the best RFID encoding configuration for encoding the type of the RFID media based on the signal strength. 
     For example, the processing circuitry may determine the highest value of the signal strength from values of signal strength determined at step/operation  507 . The processing circuitry may determine the RFID encoding configuration that corresponds to the signal strength having the highest value, and may determine such RFID encoding configuration as the best RFID encoding configuration for encoding the type of the RFID media. 
     In some embodiments, the processing circuitry may store data and/information indicating the best RFID encoding configuration for each of a plurality of types of the RFID media in a data storage device (such as, but not limited to, the storage media  406  described above in connection with  FIG.  4   ). 
     Referring back to  FIG.  5   , subsequent to step/operation  509 , the example method  500  proceeds to step/operation  511  and ends. 
     Referring now to  FIG.  6   , an example method  600  is illustrated. In particular, the example method  600  illustrates example steps/operations of selecting an RFID encoding configuration based on a type of the RFID media in accordance with various embodiments of the present disclosure. For example, the example method  600  may include determining a type of the RFID media for encoding, selecting an RFID encoding configuration from a plurality of example RFID encoding configurations based on the type of the RFID media, causing the example rotatable antenna bracket component to rotate according to the RFID encoding configuration, and causing the example RFID printer to encode the RFID media. 
     Referring now to  FIG.  6   , the example method  600  starts at step/operation  602 . In some embodiments, subsequent to and/or in response to step/operation  602 , the example method  600  proceeds to step/operation  604 . At step/operation  604 , a processing circuitry (such as, but not limited to, the processing circuitry  402  of the RFID printer  400  described in connection with  FIG.  4    above) may determine a type of the RFID media for encoding. 
     For example, similar to those described above in connection with at least step/operation  503  of  FIG.  5   , the example RFID printer may determine the type of RFID media based at least in part on RF signals received from RFID media and/or an indication of the type of RFID media. Example types of the RFID media include, but are not limited to, anti-metal tags, normal tags, and/or the like, similar to those described above. 
     Referring back to  FIG.  6   , subsequent to and/or in response to step/operation  604 , the example method  600  proceeds to step/operation  606 . At step/operation  606 , a processing circuitry (such as, but not limited to, the processing circuitry  402  of the RFID printer  400  described in connection with  FIG.  4    above) may select an RFID encoding configuration from a plurality of example RFID encoding configurations based on the type of the RFID media. 
     As described above in connection with at least  FIG.  5   , the processing circuitry may store data and/information indicating the best RFID encoding configuration for each of a plurality of types of the RFID media in a data storage device (such as, but not limited to, the storage media  406  described above in connection with  FIG.  4   ). As step/operation  606 , the processing circuitry may retrieve data and/information from the data storage device, and determine the best RFID encoding configuration from the plurality of example RFID encoding configurations based at least in part on the RFID media type determined at step/operation  604 . For example, the processing circuitry may select an RFID encoding configuration where the value of the signal strength is the highest, as described above. 
     Referring back to  FIG.  6   , subsequent to and/or in response to step/operation  606 , the example method  600  proceeds to step/operation  608 . At step/operation  608 , a processing circuitry (such as, but not limited to, the processing circuitry  402  of the RFID printer  400  described in connection with  FIG.  4    above) may cause the example rotatable antenna bracket component to rotate according to the RFID encoding configuration. 
     In some embodiments, the processing circuitry may generate instructions based on the RFID encoding configuration selected at step/operation  606 . For example, the instructions may include an indication of antenna angle according to the RFID encoding configuration selected at step/operation  606 . In some embodiments, the antenna angle defines the rotation angle of the example RFID antenna component. 
     In some embodiments, the processing circuitry may transmit instructions to one or more actuators and/or motors that are connected to a knob portion of the example rotatable antenna bracket component, and the one or more actuators and/or motors may cause the knob portion of the example rotatable antenna bracket component to rotate according to the RFID encoding configuration selected at step/operation  606 . Additionally, or alternatively, the processing circuitry may cause instructions to rotate the knob portion to be rendered on a user interface (for example, a display on the RFID printer), and a user may rotate the knob portion based on the instructions. 
     Referring back to  FIG.  6   , subsequent to and/or in response to step/operation  608 , the example method  600  proceeds to step/operation  610 . At step/operation  610 , a processing circuitry (such as, but not limited to, the processing circuitry  402  of the RFID printer  400  described in connection with  FIG.  4    above) may cause the example RFID printer to encode the RFID media. 
     For example, the example antenna component may transmit an RF signal to the RFID media at the antenna angle according to the RFID encoding configuration to encode the RFID media. As described above, the antenna angle may be determined based on the RFID media type. For example, if the RFID media is an anti-metal RFID tag, the RFID antenna component may be rotated to be positioned above the RFID media so that the RFID antenna component encodes the RFID media from the top of the RFID media. As another example, if the RFID media is a normal RFID tag, the RFID antenna component may be rotated to be positioned below the RFID media so that the RFID antenna component encodes the RFID media from the bottom of the RFID media. As another example, the RFID antenna component may be rotated to a position where the strength of the signal for the RFID media is the highest for encoding the RFID media. 
     As described above, the RFID printer may embed digital data (such as, but not limited to, the unique tag ID number) in the RF signal. Upon receiving the RF signal, the IC in the RFID inlay of the RFID tag may store the digital data (such as, but not limited to, the unique tag ID number) in the memory circuitry of the IC. 
     Referring back to  FIG.  6   , subsequent to and/or in response to step/operation  610 , the example method  600  proceeds to step/operation  612  and ends.
