Millimeter-wave Partially Dielectric Filled Waveguide Reflectarray Antenna

Abstract

Design and characteristics of millimeter-wave waveguide reflectarray antenna are considered. A specific feature of the presented antenna is a protective plastic cover that partially fills waveguides and, thus, provides additional phase correction as well. As a result, the waveguide reflectarray antenna has the relative bandwidth of 57% and 27.6 dB peak directivity. The proposed design allows manufacturing with the cheap laser-cutting and 3D printing techniques.
