Abstract :
An electrically small, pattern reconfigurable Yagi antenna is designed fabricated and measured. Two directors are located on the two opposite sides of the driver. A pin diode is used on the bottom of the director to switch the beam pattern. The measured maximum realised gain of the antenna is 8.5 dB and the front-to-back ratio is 7 dB.
