Abstract
A compact frequency and polarization reconfigurable antenna is presented. The antenna is based on a square-shaped radiating patch along with two parasitic strip lines fabricated on the single layer roger substrate. Pin diodes are placed between the patch and the parasitic strip line. The antenna comprises of dual port for polarization diversity and utilizes pin diodes for frequency diversity. The antenna can change at three different set of resonant frequencies along with 00 and 900 linear polarization state. The antenna operates at four different modes and achieves cross-polarization isolation of -15dB in all operating modes. The prototype is fabricated and its performances are validated using measurements.
