Abstract

The invention discloses a 3-bit phase-adjustable microstrip reflection unit, comprising a three-layer dielectric substrate, a metal floor, a structural unit printed on a first dielectric substrate, metal screws for grounding and fixing, and a direct current feeder Structure, the structural unit is composed of a metal circular patch printed on the first dielectric substrate, 8 identical phase delay lines and 8 PIN diodes loaded. Compared with the prior art, the present invention has the advantages that the volume of the reflection unit is smaller, the 3-bit compensation phase adjustment can be realized, and the phase compensation is accurate High rate, and the loss of the reflection unit is small, and has a wide operating bandwidth. The invention can be used in the fields of radar system, long-distance communication, space exploration and the like, and has good economic benefits.

Description

technical field [0001] The invention belongs to the technical field of microwave and millimeter wave antennas, and relates to a 3-bit phase-adjustable microstrip reflection unit. Background technique [0002] In recent years, in the fields of radar system, long-distance communication and space exploration, the application of microstrip reflectarray antenna has become more and more extensive. Compared with traditional large-diameter antennas, such as parabolic antennas and array antennas, microstrip reflectarray antennas have the advantages of small size, low profile, light weight, easy deployment, and low cost. Antennas with reflector arrays also show great potential in reconfigurability, beamforming, and multi-frequency operation. Therefore, the microstrip reflectarray antenna will have broad application prospects in the future with its superior performance. [0003] A microstrip reflectarray antenna is mainly composed of a reflector and a feed. Traditional microstrip ref...
