In this paper, polarization diversity antenna system is implemented by using two orthogonally placed printed dipole antennas to achieve the vertical and horizontal polarization for ISM band applications. Simulation, fabrication & measurements are carried out for polarization diversity printed dipole antenna at 2.4GHz center frequency. Here two orthogonal printed dipoles are simulated in HFSS simulation software and are fed by using via balun structure. A PIN diode (HSMP 1321) is used to switch between vertical and horizontal polarization for the respective antenna and the specified polarization is achieved.
