The invention relates to the technical field of antennas, and discloses a filter phase shifter and an antenna, wherein the filter phase shifter includes a phase shifter component and a filter component, and the phase shifter component includes a first substrate and phase shifter circuits respectively arranged on the first substrate and the phase-shifting formation, the phase-shifting circuit is a microstrip line structure, the filter component includes a grounding cavity and a filtering circuit inside the grounding cavity, the grounding cavity is connected to the phase-shifting formation, and the first end of the filtering circuit is connected to the phase-shifting circuit, the second end of the filter circuit is connected with the transmission circuit. A filter phase shifter and an antenna provided by an embodiment of the present invention integrate a microstrip phase shifter with a stripline or a suspended stripline filter component, which is beneficial to reduce the loss of the phase-shift filter module, thereby reducing The loss of the feeding system is reduced, the gain of the antenna system is improved, and the network coverage effect and communication quality are improved.
Description
technical field [0001] The invention relates to the technical field of antennas, in particular to a filter phase shifter and an antenna. Background technique [0002] The electronically adjustable antenna uses a phase shifter to change the phase distribution of the radiating elements to adjust the radiation beam, which is a key component of the electrically adjustable antenna. In the prior art, there are mainly conductor phase shifters and dielectric phase shifters. Among them, the conductor phase shifter realizes the phase change by sliding the conductor and changing the physical length of the conductor. Conductor phase shifters are mainly divided into metal strip line type and microstrip line type. The conductor sliding phase shifter based on the principle of microstrip can be made by PCB (Printed Circuit Board). The PCB process has the advantages of precise etching, easy debugging, and low profile. Therefore, the microstrip phase shifter becomes an important research ...
