Implementation and simulation of commercial RF switch integration with steerable square loop antenna

For the first time, integration of a commercial single-pole four-throw RF switch with beam steerable square loop antenna is presented. By controlling the switch bias the high gain tilted beam of the antenna can be steered electronically in all the four space quadrants. A model of the complete integrated switch with the antenna has been developed and simulated. Further, for achieving distortion-free patterns and error-free simulation comments are made on the placement of the RF switch and associated meshing considerations. For the test band (4.3-5.0GHz) the antenna generates a steerable tilted beam with a directivity of 8.0dBi±0.4dB. © 2011 The Institution of Engineering and Technology.
