The efficiency and beam-scanning performance of a compact, beam reconfigurable antenna are presented. The proposed design provides a 360° reconfigurable bidirectional radiation pattern in the horizontal plane by using phase variations between its 3 ports. Antenna miniaturization is achieved by dielectric loading. The miniaturized designs are presented for 4 different permittivity values so that the resonant frequency is shifted from 2.46 GHz to 2.16 GHz, 1.95 GHz and 1.8 GHz. The simulated results show good linear beam-scanning despite a decrease in antenna efficiency.
