Problems solved by technology

However, the size of the duplexer is large, and the working frequency band of the duplexer cannot cover the entire microwave communication frequency band, resulting in a wide variety of microwave equipment
Using separate receive and transmit antennas can avoid the use of duplexers, but separate receive and transmit antennas require more deployment space and are more expensive

Embodiment Construction

[0041]In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0042] In microwave communication, in order to increase the transmission power of microwave signals, reflector antennas are generally used as transmission antennas. The beam of the reflector antenna is narrow and the energy is concentrated, which is suitable for microwave communication with high frequency. Microwave communication is generally poin...

Abstract

Embodiments of the present invention provide a reflector antenna and a reflector antenna feed. The reflector antenna feed includes: a transmit antenna array and a receive antenna array, where the transmit antenna array includes at least two transmit antenna units, the receive antenna array includes at least two receive antenna units, and a phase center of the transmit antenna array coincides with that of the receive antenna array, where at least one coupling unit is disposed between at least one group of a transmit antenna unit and a receive antenna unit that are adjacent to each other.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of antennas, in particular to a reflector antenna and a feed source thereof. Background technique [0002] Antenna is a key device in wireless communication and microwave communication, it can realize mutual conversion between high-frequency electrical signal and wireless signal or microwave signal. In wireless and microwave communications, antennas are used to transmit or receive wireless or microwave signals. [0003] The reflector antenna is the most used in microwave communication. The reflector antenna includes a feed source and a reflector. In the transmitting state, the signal sent by the feed source radiates outward through the reflection of the reflective surface. The received signal is reflected into the feed and transmitted to the RF circuit connected to the feed. Since the transceiving link of the reflector antenna needs to share the reflector and the feed source, if the t...
