Performance analysis of collinear beam-steering array antenna

Abstract

In the proposed design, a collinear beam-steering array antenna is designed and analyzed. The proposed antenna has used corporate feeding to have improved characteristics of array antenna. A single band at 2.45 GHz is observed for single element antenna whereas multiband response is obtained in case of 1 × 4 array antenna. The antenna gain of 3.94 and 6.53 dB are obtained for single element and array antenna, respectively. Further beam-steering characteristics is observed and analyzed with variation in phase of feeding signal in case of proposed collinear array antenna. The compact size and beam-steering features make the antenna suitable for intelligent wireless communication.
