Abstract :
A star antenna with four symmetrical feeding points is proposed for switched beam applications. The feeding points are located on the four apexes of its 8 arms and when excited one by one, generate four tilted beams of the same characteristics in different quadrant, thus yielding a beam steerable antenna. Also, the return losses of the antenna under different feed configurations remain the same. The gain and AR for the antenna for each of the feed configuration are 8.2 dBi and 12.12 dB, respectively, with polarization dominance in the E0 direction.
