Spatial Polarization Characteristic of orthogonal polarization binary array antenna

Abstract

Antenna polarization states always vary with scan direction which can be named as Spatial Polarization Characteristic (SPC) of antenna. We present a novel antenna module named orthogonal polarization binary array antenna (OPBAA). The advantage of the design is its simple design and prominent SPC. Which can be used for polarimetric application. The theoretical model is derived and spatial polarization characteristic is especially analyzed. Measurement results of an OPBAA formed by two horns are analyzed to verify the conclusions. The OPBAA can reduce the complexity of the communication system which has good application prospect in the future.
