1. An antenna element which comprises:
- at least three substantially parallel electrically conductive plates, at least two of which are mutually adjacent and contain respective, mutually aligned apertures; and
one or more stripline conductors arranged to create radiative electromagnetic excitations of the apertures when said stripline conductor or conductors are energized by one or more suitable radiofrequency voltage sources.

Abstract
An antenna element is provided which responsive in multiple frequency bands, has symmetric beam patterns, and is easily and cheaply fabricated. The antenna element includes at least three conductive plates arranged in a stack At least one pair of adjacent plates contain apertures that are mutually aligned relative to the stacking direction. The antenna element further includes at least one air stripline arranged to create radiative electromagnetic excitations of the apertures when the stripline or striplines are energized by a suitable radiofrequency voltage source or sources.
