Square Microstrip Antenna with Frequency and Polarization Reconfigurability
The design of a microstrip square patch antenna with dual reconfigurability is presented in this paper. Reconfigurability in terms of frequency and polarization is called dual reconfigurability. It has been designed for 1.7GHz and 2.2GHz and also for circular and linear polarization. The U-slot is inserted in the square patch and PIN diodes are placed on the slot. By switching the PIN diodes on the slot from ON to OFF state, frequency diversity is achieved. The corners of the square patch are truncated and the PIN diodes are placed on the truncated corners.
