Abstract
The invention discloses an X-waveband microstrip reflection unit, which comprises a dielectric substrate, a metal circular patch printed on the dielectric substrate, eight sections of same phase delay lines printed on the front and back surfaces of the dielectric substrate, an air layer and a metal floor. And controllable adjustment of the unit reflection phase is realized by adjusting the on-off of the metal circular patch and the phase delay line at different positions. Compared with the prior art, the X-waveband microstrip reflection unit has the advantages of being small in size, simple in design, low in cost, easy to manufacture and the like, the reflection unit has wide bandwidth, the technical problem that a microstrip reflection array antenna is narrow in bandwidth is solved, in addition, the reflection unit also has reconfigurable potential, and the X-waveband microstrip reflection unit can be widely applied to the fields of radar systems, remote communication, spaceflight detection and the like.
Description
technical field [0001] The invention belongs to the technical field of microwave and millimeter wave antennas, and relates to an X-band microstrip reflection unit. Background technique [0002] In recent years, microstrip reflectarray antennas have been widely used in the fields of radar systems, long-distance communications and aerospace exploration. Compared with traditional large-aperture 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. With the in-depth research of researchers, microstrip reflectarray antennas Reflectarray antennas also show great potential in terms of reconfigurability, beamforming, and multi-frequency operation. Therefore, the microstrip reflectarray antenna will have broad application prospects in the future due to its superior performance. [0003] The microstrip reflectarray antenna is mainly composed of a reflectar...
