Background

With the development of radio frequency schemes and technologies and the demands of application scenarios, the demands of dual-band and multi-band horizontal plane high-gain antennas, such as a graphic antenna or a router antenna for an unmanned aerial vehicle airport, are increasing nowadays. However, in the conventional multi-band antenna, in order to achieve higher gain at the same time in the horizontal plane under different frequency bands, the dimension in the height direction needs to be higher, which is contrary to the practical application environment of the antenna, and it is difficult to ensure that the radiation pattern of the horizontal plane reaches an ideal state under the condition that the same antenna achieves multiple frequency bands. Therefore, an antenna which can meet the horizontal radiation patterns of various frequency bands in multiple frequency bands and realize higher horizontal gain under the condition of relatively lower height is urgently needed.

Detailed Description

Referring to fig. 1 to 10, an embodiment of the present application provides a dual-band high-gain antenna 1, which includes a circuit board 10, a duplexer 11, a first antenna oscillator 12 and a second antenna oscillator 13, wherein the duplexer 11, the first antenna oscillator 12 and the second antenna oscillator 13 are all disposed on the circuit board 10 and electrically connected to the circuit board 10, a first signal end 111 of the duplexer 11 is electrically connected to the first antenna oscillator 12, a second signal end 112 of the duplexer 11 is electrically connected to the second antenna oscillator 13, and frequency bands of the first antenna oscillator 12 and the second antenna oscillator 13 are different.

As can be appreciated, since the diplexer 11 can realize frequency band separation and support for different frequency bands, mutual interference between different frequency bands can be reduced and can adapt to application scenarios of different frequency bands by arranging the diplexer 11 between the first antenna oscillator 12 and the second antenna oscillator 13, and wider communication coverage capability is provided. Furthermore, by reasonable antenna design and layout, and by selecting the appropriate antenna elements and diplexer 11, a higher level gain can be achieved at a relatively low antenna height. Thus, the transmission distance and the receiving quality of the signal can be improved, and the communication performance is enhanced.

Specifically, the first antenna element 12 is a 5G antenna element, and the second antenna element 13 is a 2.4G antenna element.

Preferably, the first signal end 111 of the duplexer 11 is a high frequency port, and the second signal end 112 of the duplexer 11 is a low frequency port. More specifically, the first antenna element 12 is connected to the high-frequency port of the duplexer 11 through a cable or a microstrip line, and the second antenna element 13 is connected to the low-frequency port of the duplexer 11 through a cable or a microstrip line.

It will be appreciated that the low frequency port of the diplexer 11 is used to receive or transmit signals at a lower frequency, and the high frequency port of the diplexer 11 is used to receive or transmit signals at a higher frequency, so that frequency band separation can be achieved by the diplexer 11, thereby enabling support for different frequency bands.

Alternatively, the type of the diplexer 11 may be, but is not limited to, an SPDT (single polarity dual channel) or an SP4T (four channel single polarity) electronic switch diplexer 11. Can be selected according to actual requirements.

Preferably, the length of the circuit board 10 is 140mm-150mm, the width is 40mm-50mm, and the thickness is 0.8mm-1.4mm.

Alternatively, as a preferred embodiment of the present application, the circuit board 10 has a length of 145mm, a width of 45mm, and a thickness of 1.2mm. It will be appreciated that such a small size design may make the antenna more compact, convenient to integrate into various devices or modules, and suitable for space-constrained applications.

Preferably, with continued reference to fig. 1 and 2, the duplexer 11 further includes a third signal terminal 113, and the third signal terminal 113 of the duplexer 11 is connected to a receiver or transmitter module of the wireless communication device 14. Specifically, the third signal terminal 113 is a common terminal.

It will be appreciated that this arrangement facilitates connection of the device to the external wireless communications device 14.
