DETAILED DESCRIPTION

Referring to FIG. 1, in one aspect, the present disclosure is directed to a wireless receiving system 200. The wireless receiving system 200 may be easily integrated into an electronic device and may be applicable or readily adaptable to all technologies. Technical advantages are generally achieved by the wireless receiving system 200 according to embodiments of the present disclosure. Herewith the wireless receiving system 200 is described below with FIG. 1.

The subject disclosure provides the wireless receiving system 200 in accordance with the subject technology. Various aspects of the present technology are described with reference to the drawings. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of one or more aspects. It can be evident, however, that the present technology can be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form to facilitate describing these aspects. The word “exemplary” is used herein to mean “serving as an example, instance, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

FIG. 1 is a block diagram of the wireless receiving system 200 according to some embodiments of the present disclosure. As shown in FIG. 1, the wireless receiving system 200 proposed by the present invention includes a first antenna device 210, a second antenna device 220 and a wireless receiving device 100.

In structure, the first antenna device 210 and the second antenna device 220 are electrically connected to the wireless receiving device 100. It should be noted that when an element is referred to as being “electrically connected” to another element, it can be directly connected or coupled to the other element or intervening elements may be present. For example, the first antenna device 210 and the second antenna device 220 can be built-in antennas that are directly electrically connected to the wireless receiving device 100, or the first antenna device 210 and the second antenna device 220 can be external antennas that are indirectly connected to the wireless receiving device 100 through circuits or another device.

In some embodiments, the first antenna device 210 receives the first integrated signal. The first integrated signal includes the first frequency band signal 181a of the global positioning system (GPS) and the first frequency band signal 171 of the wireless wide area network (WWAN). The second antenna device 220 receives the second integrated signal. The second integrated signal includes the second frequency band signal 182a of the global positioning system and the second frequency band signal 172 of the wireless wide area network.

By implementing the first frequency band signal 181a of the global positioning system and the second frequency band signal 182a of the global positioning system on the first antenna device 210 and second antenna device 220 respectively, the dual frequency bands of the global positioning system are prevented from affecting each other, which is conducive to the wireless receiving device 100 subsequently enhancing the efficiencies of the first frequency band signal 181a of the global positioning system and the second frequency band signal 182a of the global positioning system.

In a control experiment, the antennas of various frequency bands of the global positioning system and the antennas of the wireless wide area network were separated, resulting in an excessively large size. Compared with the aforementioned control experiment, each of the first antenna device 210 and the second antenna device 220 is designed to receive signals from the global positioning system and the wireless wide area network together. Therefore, the first antenna device 210 and the second antenna device 220 can effectively reduce the size or area.

Following the above, although each of the first antenna device 210 and the second antenna device 220 is designed to receive the signals of the global positioning system and the wireless wide area network together, the wireless receiving device 100 can improve the reception quality of the first frequency band signal 181a and the second frequency band signal 182a of the global positioning system, so as to prevent the first frequency band signal 181a of the global positioning system and the second frequency band signal 182a of the global positioning system from being affected by the wireless wide area network.

In order to further elaborate on the specific structure of the wireless receiving device 100, please continue to refer to FIG. 1. In some embodiments of the disclosure, the wireless receiving device 100 includes a first extractor 110, a second extractor 120, a first amplifier 150 and a second amplifier 160. In structure, the first extractor 110 is electrically connected to the first antenna device 210, the first amplifier 150 is electrically connected to the first extractor 110, the second extractor 120 is disconnected from the first extractor 110, the second extractor 120 is electrically connected to the second antenna device 220, and the second amplifier 160 is electrically connected to the second extractor 120.

For example, the first amplifier 150 can be a low-noise amplifier in the frequency band range of the first frequency band signal 181a of the global positioning system, and the second amplifier 160 can be another low-noise amplifier in the frequency band range of the second frequency band suitable for the global positioning system.

In some embodiments, the first extractor 110 separates the first integrated signal into the first frequency band signal 181a of the global positioning system and the first frequency band signal 171 of the wireless wide area network, so that the first frequency band signal 181a of the global positioning system cannot be affected by the wireless wide area network. The first amplifier 150 amplifies the first frequency band signal 181a of the global positioning system to output the amplified first frequency band signal 181b of the global positioning system, thereby improving the signal reception quality of the global positioning system. Since the first frequency band signal 181a of the global positioning system only passes through the first extractor 110 before passing through the first amplifier 150, the path loss is effectively reduced.

On the other hand, the second extractor 120 separates the second integrated signal into the second frequency band signal 182a of the global positioning system and the second frequency band signal 172 of the wireless wide area network, so that the second frequency band signal 182a of the global positioning system cannot be affected by the wireless wide area network. The second amplifier 160 amplifies the second frequency band signal 182a of the global positioning system to output the amplified second frequency band signal 182b of the global positioning system, thereby improving the signal reception quality of the global positioning system. Since the second frequency band signal 182a of the global positioning system only passes through one second extractor 120 before passing through the second amplifier 160, the path loss is effectively reduced.

Furthermore, each of the first frequency band signal 181a of the global positioning system and the second frequency band signal 182a of the global positioning system only passes through one extractor before amplification, so that the intensity of the amplified first frequency band signal 181b of the global positioning system output by the first amplifier 150 can be approximately close to the intensity of the amplified second frequency band signal 182b of the global positioning system output by the second amplifier 160. In this way, there is no mismatch in the dual-band signals of the global positioning system.

Regarding the structure of the first extractor 110, in some embodiments of the present disclosure, the first extractor 110 has a GPS signal terminal 111, a WWAN signal terminal 112 and a common terminal 113. In structure, the common terminal 113 of the first extractor 110 is electrically connected to the first antenna device 210, and the GPS signal terminal 111 of the first extractor 110 is electrically connected to the input terminal 151 of the first amplifier 150.

In some embodiments, the common terminal 113 of the first extractor 110 receives the first integrated signal including the first frequency band signal 181a of the global positioning system and the first frequency band signal 171 of the wireless wide area network from the first antenna device 210, the WWAN signal terminal 112 of the first extractor 110 outputs the first frequency band signal 171 of the wireless wide area network, and the GPS signal terminal 111 of the first extractor 110 outputs the first frequency band signal 181a of the global positioning system.

For example, the GPS signal terminal 111 of the first extractor 110 can be a band-pass filter terminal for the first frequency band signal 181a of the global positioning system, and the band-pass filter terminal can include a band-pass filter. The aforementioned band-pass filter terminal only allows the first frequency band signal 181a of the global positioning system in the first integrated signal to pass through. The WWAN signal terminal 112 of the first extractor 110 can be a notch filter terminal for the first frequency band signal 181a of the global positioning system, and the notch filter terminal can include a notch filter. The aforementioned notch filter terminal can filter out the first frequency band signal 181a of the global positioning system from the first integrated signal, thereby leaving the first frequency band signal 171 of the wireless wide area network to pass through. The common terminal 113 of the first extractor 110 is not equipped with a filter and allows signals in the entire frequency range to pass through.

Similarly, regarding the structure of the second extractor 120, in some embodiments of the present disclosure, the second extractor 120 has a GPS signal terminal 121, a WWAN signal terminal 122 and a common terminal 123.

The WWAN signal terminal 122 of the second extractor 120 outputs the second frequency band signal 172 of the wireless wide area network, and the GPS signal terminal 121 of the second extractor 120 outputs the second frequency band signal 182a of the global positioning system.

For example, the GPS signal terminal 121 of the second extractor 120 can be a band-pass filter terminal for the second frequency band signal 182a of the global positioning system, and the band-pass filter terminal can include a band-pass filter. The aforementioned band-pass filter terminal only allows the second frequency band signal 182a of the global positioning system in the second integrated signal to pass through. The WWAN signal terminal 122 of the second extractor 120 can be a notch filter terminal of the second frequency band signal 182a of the global positioning system, and the notch filter terminal can include a notch filter. The aforementioned notch filter terminal can filter out the second frequency band of the global positioning system from the second integrated signal, thereby leaving the second frequency band signal 172 of the wireless wide area network to pass through. The common terminal 123 of the second extractor 120 is not equipped with a filter and allows signals in the entire frequency range to pass through.

In FIG. 1, the wireless receiving device 100 includes a signal integration unit 230 (e.g., a circuit). In structure, the signal integration unit 230 is electrically connected to the WWAN signal terminal 112 of the first extractor 110, the output terminal 152 of the first amplifier 150 and the output terminal 162 of the second amplifier 160.

In some embodiments, the signal integration unit 230 can combine and output the first frequency band signal 171 of the wireless wide area network, the amplified first frequency band signal 181b of the global positioning system and the amplified second frequency band signal 182b of the global positioning system to the first port 191 of wireless signal module 190. On the other hand, the second extractor 120 outputs the second frequency band signal 172 of the wireless wide area network to the second port 192 of the wireless signal module 190.

In order to further elaborate on the specific structure of the signal integration unit 230 in the wireless receiving device 100, please refer to FIG. 2. FIG. 2 is a block diagram of a wireless receiving device 100 according to some embodiments of the present disclosure.

Those with ordinary skilled in the art can flexibly adjust the connection relationship between the terminals of the third extractor 130 and the fourth extractor 140 based on the aforementioned functions, which will not be described in detail.

Regarding the structure of the third extractor 130, in some embodiments of the present disclosure, the third extractor 130 has a GPS signal terminal 131, a WWAN signal terminal 132 and a common terminal 133.

The third integrated signal includes the amplified second frequency band signal 182b of the global positioning system and the first frequency band signal 171 of the wireless wide area network.

For example, the GPS signal terminal 131 of the third extractor 130 can be a band-pass filter terminal for the amplified second frequency band signal 182b of the global positioning system, and the band-pass filter terminal can include a band-pass filter. The aforementioned band-pass filter terminal only allows the amplified second frequency band signal 182b of the global positioning system to pass through. The WWAN signal terminal 132 of the third extractor 130 can be a notch filter terminal for the amplified second frequency band signal 182b of the global positioning system, and the notch filter terminal can include a notch filter. The aforementioned notch filter terminal only filters out the amplified second frequency band signal 182b of the global positioning system, thereby allowing the first frequency band signal 171 of the wireless wide area network to pass through.

The common terminal 143 of the fourth extractor 140 outputs the fourth integrated signal.

For example, the GPS signal terminal 141 of the fourth extractor 140 can be a band-pass filter terminal for the amplified first frequency band signal 181b of the global positioning system, and the band-pass filter terminal can include a band-pass filter. The aforementioned band-pass filter terminal only allows the amplified first frequency band signal 181b of the global positioning system to pass through. The integrated signal terminal 142 of the fourth extractor 140 can be a notch filter terminal for the amplified first frequency band signal 181b of the global positioning system, and the notch filter terminal can include a notch filter.
