Abstract
A microstrip antenna which includes a ground member, a dielectric element mounted on the ground member and a radiating element on the dielectric element, has been improved by means of a distinct grounding ring of conductive material which is spaced apart from and extends around the radiating element. The grounding ring is connected to a ground member, thereby laterally isolating the antenna and permitting a closer spacing with adjacent antennas. The gap between the radiating element and the grounding ring is different in different directions.
