摘要
A novel method of steering antenna beam in its E-plane is introduced and a design of wideband pattern reconfigurable antenna with enhanced gain is proposed in this paper. A bowtie antenna is used as the driven radiator, and two parasitic bowtie-shaped microstrip stubs with two diodes are loaded beside each arm of the driven radiator. With the introducing of a low profile artificial magnetic conductor (AMC) beneath the bowtie radiator, unidirectional radiation pattern can be obtained. By altering the working states of the diodes, the main beam of the antenna can be switched in its E-plane. The biasing circuit of the antenna is simple and easy to be implemented. The prototype of the antenna is fabricated, and good agreement can be observed between the simulated and measured results. Compared to other pattern reconfigurable antennas, the proposed antenna has advantages of a wide operating band, ability of beam switching in E-plane, and high gain. These advantages makes it a good candidate for the wireless communication systems.
