To fully realize the system potential of wireless local area networks(WAN), polarization diverse antennas must be employed to minimize fading and optimize performance in dynamic, complex electromagnetic environments. An antenna solution that is integral to a W A N PCMCTA card has been developed, demonstrated and the results presented here.
