Abstract

The invention provides a C-band polarization-reconfigurable microstrip planar array antenna in the technical field of communication. The C-band microstrip planar array antenna comprises three dielectric substrates. A polarization-reconfigurable network comprises a 3dB directional coupler and two one-from-two RF switches. Through switching on or switching off the one-from-two RF switches, a working polarization manner in operation of the antenna can be freely selected. Through using the polarization-reconfigurable network, characteristics of horizontal polarization, vertical polarization, left-handed circular polarization and right-handed circular polarization in the antenna can be realized. The C-band polarization-reconfigurable microstrip planar array antenna has advantages of high gain, low profile, small size, high directional diagram consistency, etc. The C-band polarization-reconfigurable microstrip planar array antenna can be used in satellite and radar communication and some application occasions where multipolarization and miniaturization are required.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular, to a microstrip planar array antenna with reconfigurable polarization, especially a C-band reconfigurable microstrip planar array antenna. Background technique [0002] With the rapid development of information technology, in order to better adapt to the large-capacity and diversified development needs of wireless communication, higher requirements are also put forward for the design of antennas. According to the actual function, the reconfigurable antenna can be divided into reconfigurable frequency, reconfigurable polarization, reconfigurable pattern, and reconfigurable with arbitrary switching of various performance parameters. Reconfigurable antenna polarization is to reconfigure the polarization state of antenna radiation, avoid signal fading caused by multipath effects, and improve wireless communication quality and anti-interference ability. Choose the appropr...
