Abstract

A newly proposed electronically antenna with a reconfigurable azimuth radiation pattern, has been experimentally investigated in this work. In this design a coaxial colinear (COCO) antenna is located in the middle of a cylinder shield as an omnidirectional source. The cylindrical shield is constructed with active band reflective unit cells. The antenna has been fabricated and measured. A tunable step of 18° is realized. Front-to-back ratio in the directivity pattern is about 20 dB with the depth of null point at -34 dB and the gain of the antenna can be promoted to 9.35 dB.
