Dual-frequency antenna and antenna system

Dual-frequency antenna and antenna system

Disclosed is a dual-frequency antenna. A first phase shifter thereof is used for receiving a first signal at a first radio-frequency band and adjusting the phase shifting amount of the first signal according to a requirement for a downward inclination angle at the first radio-frequency band; a secon...

description Disclosed is a dual-frequency antenna. A first phase shifter thereof is used for receiving a first signal at a first radio-frequency band and adjusting the phase shifting amount of the first signal according to a requirement for a downward inclination angle at the first radio-frequency band; a second phase shifter is used for receiving a second signal at a second radio-frequency band and adjusting the phase shifting amount of the second signal according to a requirement for a downward inclination angle at the second radio-frequency band; a combiner is used for receiving the first signal adjusted by the first phase shifter and the second signal adjusted by the second phase shifter, combining the first signal and the second signal and then sending same to an antenna radiation unit; and the antenna radiation unit is used for receiving and transmitting the adjusted first signal and second signal input by the combiner. Also disclosed is an antenna system. By means of the method, the dual-frequency antenna in the p
