Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
It is to be noted that, unless otherwise specified, technical or scientific terms used herein shall have the ordinary meaning as understood by those skilled in the art to which this application belongs.
Example one
Referring to fig. 1, an embodiment of the present application proposes an antenna system, which includes: a first radio frequency path connected to the first antenna 1; a second radio frequency path connected to the second antenna 2; the switch 3 is connected with the first radio frequency path and the second radio frequency path, and is used for gating the first radio frequency path and/or the second radio frequency path to enable the first antenna 1 and/or the second antenna 2 to transmit signals; the switch 3 is disposed at the starting end of the first rf path and the second rf path.
Specifically, the antenna system provided in this embodiment is a dual-antenna system, and includes a first radio frequency path and a second radio frequency path connected to the first antenna 1 and the second antenna 2, respectively, and a switch 3 disposed at the start ends of the first radio frequency path and the second radio frequency path, where the switch 3 is connected to the first radio frequency path and the second radio frequency path, respectively, and when transmitting a signal, may gate one of the first radio frequency path or the second radio frequency path to enable one of the first antenna 1 or the second antenna 2 to transmit the signal, that is, to enable the single-connection transmission of the dual-antenna system, and may receive the signal through the first antenna 1 and the second antenna 2 at the same time, in this design, the switch 3 is usually enabled to perform signal transmission for the radio frequency path connected to the antenna with the higher signal strength in the first antenna 1 and the second antenna 2, or may also enable the first radio frequency path and the second radio frequency path to perform signal transmission through the switch 3 at the same time, that is, that the first antenna 1 and the second antenna 2 may perform signal transmission at the same time, that is, that the dual-antenna system performs dual-antenna transmission connection. Because the switch has loss and the radio frequency amplifier in the radio frequency path has gain, if the change-over switch 3 is placed at the output end of the radio frequency amplifier, the loss of the output power of the radio frequency amplifier can be caused, and in the technical scheme adopted by the application, the change-over switch 3 is arranged at the starting end of the first radio frequency path and the second radio frequency path, the output power of the radio frequency amplifier can not be influenced, so that the loss caused by inserting the switch can be reduced to the maximum extent; it should be noted that the switch 3 controls only the transmission of signals in the antenna system, and does not control the reception of signals.
According to the antenna system, the change-over switch is arranged at the starting ends of the two radio frequency paths, so that the output ends of the two radio frequency power amplifiers are not provided with the switch, and the loss of transmitting and receiving signals caused by the insertion of the switch can be saved; by arranging the two radio frequency power amplifiers and the two duplexers, the two radio frequency power amplifiers and the two duplexers can be respectively arranged close to the two switches, the loss caused by switching paths can be reduced, and the radio frequency power amplifier and the duplexer of each path are respectively matched with an antenna and a radio frequency channel, so that the linearity can meet the best matching debugging.
Specifically, the antenna system provided in this embodiment may be applied to, but not limited to, electronic devices such as a mobile phone, taking the mobile phone as an example, the first antenna 1 and the second antenna 2 may be respectively disposed at the top and the bottom of the mobile phone, when a user uses the antenna system, the hand or other parts of the user may shield the first antenna 1 or the second antenna 2, and the performance of the shielded antenna may be reduced.
According to the above list, the present application provides an antenna system, which is a dual-antenna system, and includes a first rf path and a second rf path respectively connected to a first antenna 1 and a second antenna 2, and a switch 3 connected to the first rf path and the second rf path is provided to gate the first rf path and/or the second rf path, so as to transmit signals through the first antenna 1 and/or the second antenna 2, and by disposing the switch 3 at the start end of the first rf path and the second rf path, loss caused by inserting a switch can be reduced to the greatest extent, which is beneficial to improving antenna performance.
Further, referring to fig. 1, in an implementation, the first rf path includes a first rf power amplifier 41 and a first duplexer 42; the second radio frequency path includes a second radio frequency power amplifier 51 and a second duplexer 52; the switch 3 is connected to the input terminals of the first rf power amplifier 41 and the second rf power amplifier 51.
Specifically, since the first antenna 1 and the second antenna 2 are arranged at a relatively long distance in the electronic device, in order to reduce the path loss of the antenna system, in the technical scheme adopted in the present application, the first rf path couples the even first rf power amplifier 41 and the first duplexer 42, the second rf path includes the second rf power amplifier 51 and the second duplexer 52, the first duplexer 42 and the second duplexer 52 are respectively connected to the output ends of the first rf power amplifier 41 and the second rf power amplifier 51, and the switch 3 is connected to the input ends of the first rf power amplifier 41 and the second rf power amplifier 51; in the present dual antenna system, two rf paths share a duplexer and an rf power amplifier, because the first antenna 1 and the second antenna 2 are located at relatively far positions in the electronic device, and the duplexer and the rf power amplifier can only be located close to one antenna, if the first antenna 1 is switched to another antenna, if the second antenna 2 is switched, path loss is very large, and because impedances of the two antennas and the path are not consistent, the performance of the duplexer and the rf power amplifier can only take care of one path of signal, which results in another path of signal being poor, and particularly, it is difficult to meet the rf performance index under the condition that the requirement of 4G/5G on linearity is high, in the technical solution adopted in the present application, the two rf paths are respectively provided with the duplexer and the rf power amplifier, the first duplexer 42 and the first rf power amplifier 41 can be set close to the first antenna 1 and matched to the first antenna 1 and the first rf path, and the second duplexer 52 and the second rf power amplifier 51 can be set close to the second antenna 2 and the rf power amplifier 51, and the two rf power amplifiers can be designed to reduce the loss effectively and the path loss of each rf signal can be adjusted; compared with a scheme that two radio frequency paths share one duplexer and one radio frequency power amplifier, the method can increase one duplexer and one radio frequency power amplifier, or can also utilize the arrangement of two radio frequency power amplifiers and two duplexers of the current 4G/5G CA and ENDC, namely, the cost is not increased.
