Summary:
In this article, two types of the beam reconfigurable antenna are designed and their performances are analyzed. The operation mechanisms of the antennas and their optimization processes using PIN diodes are introduced. Both of them are designed to operate over DCS 1800 and PCS 1900 frequency bands. The electrical shapes of the proposed antennas are symmetric about vertical center axis. The proposed antennas alternate their beam directions with essentially no input impedance difference. The equivalent linear circuit models of the PIN diode are illustrated, corresponding to on and off states. The simulated and measured results show that the proposed antennas can clearly change their radiation patterns by controlling the switching state.
