Abstract
A parallel-plate antenna or antenna array suitable for operation at millimeter wave frequencies. The antenna includes an antenna element having a ground plane with a slot and a pair of parallel plates connected to the ground plane. The parallel plates extend generally perpendicularly from the ground plane. In plan view, the slot is arranged between the parallel plates. The antenna also includes a feed operably coupled with the slot for feeding the slot during operation so as to generate a circularly polarized signal for radiation.
