Abstract

Embodiments relate to two-dimensional antenna arrays. In one embodiment, an antenna array includes single-ended fed patch antennas and differentially fed patches. Field polarization of the radiated and/or received EM waves is different by 90 degrees for each different antenna type. Thus, an aligned polarization pattern can be achieved using orthogonal feeding direction for single-ended and differential patches. Embodiments can be used in radar or virtually any other 2D array antenna system.
