Abstract
Switchable magnetic media and shorting posts are popular in controlling both the radiation characteristics and size of microstrip patch antennas. In this paper, a ferrite-based shorted circular patch antenna is designed to demonstrate magnetically switchable dual frequency response. The DC magnetic bias, applied normally to the ferrite substrate, allowed the antenna size to be reduced by as much as 80%. Optimized length and position of the reactive post exhibited improved impedance bandwidth with excellent frequency tuning capabilities. Commercial software is used to simulate resonance and radiation responses of the designed antenna.
