Antenna mount

Various embodiments are described that relate to an antenna mount. Multiple antennas can be mounted on the antenna mount. These antennas can work together or be independent of one another. In an example of working together, one antenna can be a transmission antenna while the second antenna can be a reception antenna. The transmission antenna and reception antenna can function with regard to the same communication signal.

BACKGROUND

A plurality of users can employ communication devices in order to communicate with one another. Individual communication devices can employ at least one antenna in order to achieve desired communication results. It is possible that communications from multiple antennas can cause interference with one another. This interference can be undesirable.

SUMMARY

In one embodiment, a housing comprises a first antenna retention portion and a second antenna retention portion. The first antenna retention portion can be configured to retain a first antenna at a first position and the second antenna retention portion can be configured to retain a second antenna at a second position. The first position and the second position can cause the first antenna and the second antenna to function without interfering with one another. Additionally, the first position can cause communication of the first antenna to be non-physically influenced by the housing.

In another embodiment, a system comprises a first antenna mount configured to support a first antenna and a second antenna mount configured to support a second antenna. The first antenna mount and the second antenna mount are physically connected to one another. The system also comprises a separator configured to separate the first antenna when mounted from the second antenna when mounted, configured to cause the first antenna to not interfere with itself, and configured to cause the second antenna to not interfere with itself.

In yet another embodiment, a system comprises a first antenna base configured to support a first antenna, a second antenna base configured to support a second antenna, and a divider configured to prevent coupling between the first antenna and the second antenna. The first antenna base, the second antenna base, and the divider can be part of the housing. The first antenna base and the second antenna base can be configured to have the first antenna and the second antenna physically align about flush with one another along a plane of their main transmission side.

DETAILED DESCRIPTION

In one embodiment, an antenna mount (e.g., multiple antenna mounts) can be used to mount multiple antennas (or antennae). This mount can allow for both antennas to operate without interference from the other and interference from itself. With this mount, multiple antennas can function together while in close proximity to one another.

The antenna mount can be a mechanical housing to two or more commercial-off-the-shelf antennas, such as wideband horn antennas. The housing can be structured such that individual antennas can be independently changed with regard to their orientation. The housing can also cause radio frequency isolation between antennas and be mounted upon a pedestal.

FIG. 1aillustrates one embodiment of a system comprising a first antenna mount110, a second antenna mount120, and a separator130.FIG. 1billustrates one embodiment of an environment140bwith a first antenna150and a second antenna160with their respective outputs170and180.FIG. 1cillustrates one embodiment of an environment140cemploying the first antenna mount110, the second antenna mount120, and the separator130. These drawings may be referred to collectively as “FIG. 1.”

The first antenna mount110and the second antenna mount120can be physically connected to one another. In one example, the first antenna mount110and the second antenna mount120can share a physical base and protrude from the base. The separator130can also be physically connected to the antenna mounts110and120, such as connecting with the physical base. The first antenna mount110can be configured to support the first antenna150and the second antenna mount120can be configured to support the second antenna160.

The separator130can improve performance of the antennas150and160. The separator130can be configured to separate the first antenna150when mounted from the second antenna160when mounted. The separator130can be configured to cause the first antenna150to not interfere with itself and can be configured to cause the second antenna160to not interfere with itself. Also, the separator130can be configured to separate the first antenna150from the second antenna160such that the first antenna150does not interfere with the second antenna160. Similarly, this can be such that the second antenna160does not interfere with the first antenna150.

WithFIG. 1b, the antennas150and160function absent the system100. The first antenna150transmits a first output170and the second antenna160transmits a second output180. In one example, the outputs170and180are signals. As one can see, the outputs170and180partially overlap and this overlap can cause interference of both outputs170and180. Oftentimes in wireless communication, interference is an undesired quality.

WithFIG. 1c, the environment140ccan cause mitigation or elimination of this interference. The separator130can be made of an absorptive material and/or be physically shaped to be absorptive, such as by including cones. With this, the separator130can prevent the outputs170and180from overlapping and therefore interfering. Additionally, the separator130being absorptive can also cause the antennas150and160, and in turn their respective outputs170and180, to not interfere with themselves. In thus, there can be a lowering (e.g., elimination) of bias from one antenna to another. If the separator130is not absorptive, then it is possible for the separator130to reflect the outputs170and180back and cause interference. In one embodiment, the outputs170and180can interfere with one another and yet not interfere with themselves by way of reflection. In this example, once the outputs170and180go beyond the system100, then they may interfere with one another. Example interference that can be eliminated with practice of innovations disclosed herein includes radio frequency (RF) coupling.

FIG. 2aillustrates one embodiment of a quasi-monostatic antenna configuration210.FIG. 2billustrates one embodiment of a bistatic antenna configuration220. These drawings may be referred to collectively as “FIG. 2.” Other configurations can be employed other than quasi-monostatic and bistatic, such as a multistatic configuration.

The two antennas150and160can be used in RF data collection bay way of different configurations, such as the quasi-monostatic antenna configuration210or the bistatic configuration220. With the quasi-monostatic antenna configuration210, the two antennas150and160can, in one embodiment, fuse into one physical antenna. With these configurations, having a rigid mounting structure, such as a structure built to pre-determined specifications, can cause symmetry between the two antennas150and160.

In one embodiment, the antennas150and160can function independently. With this, the antennas can function at different frequencies. Therefore, the system100ofFIG. 1acan conveniently function as a retainer of multiple, un-related antennas.

In one embodiment, the antennas150and160can function in an interdependent manner. In one example, the first antenna150can be a transmission antenna configured to transmit a signal (e.g., output170ofFIG. 1). The second antenna160can be a reception antenna configured to receive a response to the signal after transmission (e.g., output180ofFIG. 1). Therefore, the two antennas150and160can work together while integrated upon the system100ofFIG. 1a.

InFIG. 2, “d” and “D” represent physical separation between phase centers of the antennas150and160. In general, a smaller separation can be used in the quasi-monostatic antenna configuration210since a range to target is likely to be much greater than the physical separation between the antenna phase centers. The case when the physical separation is large relative to the range to target can be used in the bistatic antenna configuration220. “ΔR” can be considered antenna path loss that can be defined as separation between antenna beams pointed in a direction “Θ” relative to antenna normal (e.g., the direction can be arbitrary). These can be interrelated by ΔR=d sin Θ or ΔR=D sin Θ.

FIG. 3illustrates one embodiment of three views310-330of a first antenna mount arrangement. The view310illustrates a reception portion that can be used to couple the mount to a pedestal, a vehicle, or other structure. The views320and330illustrate how reception portions can be separated by a separator while still be part of one structure. In one embodiment, the first antenna mount arrangement can be constructed from a resin through employment of three-dimensional printing techniques. While not illustrated, the first antenna mount arrangement can comprise an RF-absorptive material that is placed around surface cavities.

FIG. 4illustrates one embodiment of three views410-430of a second antenna mount arrangement. View410illustrates a perspective view, view420illustrates a top-down view, and view430illustrates a forward-facing view. In one embodiment, the second antenna mount arrangement can be constructed from wood and be built by a carpenter or machine.

The first antenna mount arrangement (discussed withFIG. 5) and the second antenna mount arrangement can be designed for a zero-transition plane for potential RF-coupling between the two antennas150and160ofFIG. 1(e.g., antenna150being a transmission antenna and antenna160being a reception antenna). The two antennas150and160can be independently or dependently moved. This movement can be vertically, horizontal, and/or rotational. Further, this movement can be done by hand or done by way of an apparatus, such as instructions sent from a control system.

Additionally, movement of mount pieces themselves can occur. In one example, the separator130ofFIG. 1can be moved along the x-axis, y-axis, and/or z-axis. In another example, the first antenna mount110and the second antenna mount120can individually comprise hardware for coupling the antennas150and160ofFIG. 1to their respective mount. This hardware can be moved, such as to define polarization of emitted transverse electromagnetic waves. In this example, moving the mounting hardware can also move the antennas themselves. However, the mounting hardware can be configured to be moved without antennas coupled.

FIG. 5illustrates one embodiment of a system500comprising a construction component510and an output component520. The construction component510can build the system100ofFIG. 1or another physical object (e.g., the arrangements discussed inFIGS. 3 and 4). In one example, the construction component510can receive input parameters and use these parameters to build the system100ofFIG. 1. The construction component510can comprise manufacturing machinery employed for such a build. Once constructed, the output component520can cause an output of a finished product—such as the system100ofFIG. 1or a system described in the method700discussed below with regard toFIG. 7.

FIG. 6illustrates one embodiment of a system600comprising a processor610(e.g., a general purpose processor or a processor specifically designed for performing functionality disclosed herein) and a computer-readable medium620(e.g., non-transitory computer-readable medium). In one embodiment, the computer-readable medium620is communicatively coupled to the processor610and stores a command set executable by the processor610to facilitate operation of at least one component disclosed herein (e.g., the construction component510ofFIG. 5). In one embodiment, at least one component disclosed herein (e.g., the output component520ofFIG. 5) can be implemented, at least in part, by way of non-software, such as implemented as hardware by way of the system600. In one embodiment, the computer-readable medium620is configured to store processor-executable instructions that when executed by the processor610cause the processor610to perform a method disclosed herein, such as the method700discussed below.

FIG. 7illustrates one embodiment of a method700comprising two actions710-720. These actions710-720can be performed upon a housing. The housing can comprise a first antenna retention portion configured to retain a first antenna (e.g., the first antenna150ofFIG. 1) at a first position and a second antenna retention portion configured to retain a second antenna (e.g., the second antenna160ofFIG. 1) at a second position. At710, the first antenna can be mounted at the first position and at720, the second antenna can be mounted at the second position. The first position and the second position can cause the first antenna and second antenna to function without interfering with one another, the first position can cause communication of the first antenna to be non-physically influenced by the housing (and the same for the second position), and the first position can cause communication of the second antenna to be non-physically influenced by the housing (and conversely for the second position with respect to the first antenna).

In one embodiment, the first antenna and the second antenna can function at different frequencies or the same frequency. In one example, while functioning at different frequencies, the antennas can be horn antennas that function within a frequency band. This can be, for example, when both antennas are of a similar band.

In one embodiment, at least one antenna can be a high-band antenna. The high-band antenna can function, in one example, within a frequency range of 18 Gigahertz (GHz) to 40 GHz. In one example, the high-band antenna can be a double ridge guide horn high-band antenna.

In one embodiment, at least one antenna can be a mid-band antenna. The mid-band antenna can function, in one example, within a frequency range of 700 Megahertz, to 18 Ghz. In one example, the mid-band antenna can be a double ridge guide horn mid-band antenna.

The antennas can work together while integrated with the housing. The first antenna can be a transmission antenna configured to transmit a signal. Meanwhile, the second antenna can be a reception antenna configured to receive a response to the signal after transmission. Therefore, the antennas can function together with regard to the signal. To improve performance, the first antenna and second antenna can be positioned while retained by their respective portions. This positioning can be automated and/or performed by a technician. Example positioning can be moving the individual antennas vertically, horizontally, or rotationally. This positioning can be independent (e.g., the first antenna can be moved while the second antenna remains unmoved) or dependent. In one example, the antennas can be mid-band antennas and moving the antennas can allow for waveguide re-orientation that defines polarization of an emitted transverse electromagnetic wave.

Different configurations can be used to lower (e.g., minimize) interference for the antennas. The first antenna and second antenna can be separated by a plate such that coupling between the first antenna and the second antenna is avoided. The first antenna retention portion and the plate can be configured relative to one another such that the first antenna can be configured to not interfere with itself while retained. As an example of this, the plate can be made of and/or coated in an absorptive material to cause a result as illustrated inFIG. 1c.

The plate can be a divider configured to prevent coupling between the first antenna and the second antenna. The first antenna can be supported by a first antenna base and the second antenna can be supported by a second antenna base. The divider and the bases can be movable (e.g., raised/lowered, left/right, or forward/back) and the antennas themselves can be moved while part of the bases (e.g., rotated, horizontally, or vertically). In one example, the bases can be moved to cause the first antenna and the second antenna to physically align about flush with one another along a plane of their main transmission side (e.g., the horn part of the antennas are aligned with one another such that one antenna does not extend past another antenna).

While the methods disclosed herein are shown and described as a series of blocks, it is to be appreciated by one of ordinary skill in the art that the methods are not restricted by the order of the blocks, as some blocks can take place in different orders. Similarly, a block can operate concurrently with at least one other block.
