Abstract

A reconfigurable beam-steering antenna using a coplanar waveguide with ground with directive radiation pattern is presented. The switchable beam steering antenna composed of a loop and two dipole structures with four switches to generate six different radiation beam patterns is proposed. The antenna can select desired beam pattern by controlling switching configurations. The proposed antenna is designed to operate at 2.65 GHz with 4.2 dBi maximum gain for wireless communications. Maximum beam direction can be steered by switch on/off configurations with ±30° in the H-plane and E-plane.
