Abstract

In this paper, a compact and reconfigurable radiation pattern dipole antenna based on the Yagi-Uda antenna principle and operating at 2.5 GHz is designed. Controlling the switching states of three loaded switches allows for pattern reconfigurability. Three modes can be chosen based on the results of the simulations and measurements. In the first mode M1, a high directive- beam can be achieved by turning ON all the RF switches, and a measured peak gain of 6.7dBi is obtained with a corresponding half-power beamwidth (HPBW) of 44°. In the second mode, only the director is required to enable a less directive beam. This allows for a larger HPBW of 62° and a lower peak gain of 5.47 dBi. Finally, by disabling the reflector and director in the third mode, M3, we get an omnidirectional radiation pattern around the y-axis with a maximum measured gain of 3.8 dBi. The comparison with other prior art antennas shows that the proposed reconfigurable antenna has compact size, high gain, and simple design, making the structure a good candidate for new wireless applications.
