Abstract :
A compact PIFA with polarization and frequency agility was presented. It was shown that using groups of pin diodes the polarization can be switched between two orthogonal linear polarizations. This antenna is devoted to RF front-end of wireless systems using polarization diversity at the reception. Switching between two frequencies can also be achieved. The antenna presented can cover the entire 2.4 GHz ISM band or can be used for WiMax applications at 3.5 GHz.
