Millimeter wave High Impedance Surfaces (HIS) based antennas are designed, fabricated, and characterized for high data rate communications at frequencies around 40 GHz. HIS with different finite surface area sizes are used as a ground plane for the microstrip patch antennas to suppress the surface waves. The antenna measurements and full wave electromagnetic simulations demonstrate a wide bandwidth of 12-15% in the frequency range of 38-44 GHz with a high gain of ~6 dB and a very low cross polar contribution better than -20 dB.
