Abstract
An antenna has a conductive ground plate, a conductive first plate set above the ground plate, and a signal feed electrically connected to the ground plate and the first plate. A first distance separates the first plate from the ground plate. The first plate has two slots extending from two edges of the first plate. The two extending points of the two slots are located approximately opposite to each other, and the two slots extend around a central portion of the first plate.
