Abstract
An antenna system includes an antenna array including a number of antenna elements disposed on a substrate. Each antenna element includes a radiation layer, a ground plane layer, a feed layer and an additional ground plane layer. The ground plane layer includes a ground plane conductive layer that has a number of slots. The feed layer includes a feed structure to excite the slots. A dual polarization feature of the antenna array is realized via the slots, and the slots are separated by the ground plane conductive layer.
