1. An antenna comprising:
- a top plate comprising a plurality of contiguous planar conductive regions, wherein adjacent ones of the plurality of conductive regions define a slot therebetween;
a ground plane spaced apart from and substantially parallel to the top plate;
a plurality of legs extending from the top plate toward the ground plane, wherein the plurality of legs is equal in number to the plurality of conductive regions, and wherein each one of the plurality of legs is electrically connected to the top plate;
a feed conductor;
wherein at least a first pair of oppositely disposed legs of the plurality of legs is connected to the feed conductor; and
wherein at least a second pair of oppositely disposed legs of the plurality of legs is connected to the ground plane.

Abstract
A monolithic surface mountable monopole antenna. The antenna comprises a top plate having a plurality of conductive regions and a like plurality of legs extending away from a plane of the top plate in a direction of a ground plane. Each leg is disposed between two adjacent conductive regions. In an embodiment wherein the top plate comprises four conductive regions, two of the four legs are connected to an underlying ground plane and two of the legs are connected to a signal feed conductor.
