An antenna for a communication device is disclosed. The antenna has a structure including a ground plane and a lid component. The lid component is conductive, substantially planar and has a planform shape which is lesser in a first lid component dimension (L.sub.1) than it is in a second lid component dimension (L.sub.2) perpendicular to the first lid component dimension (L.sub.1). The ground plane is conductive and substantially planar, and the size of the ground plane is greater than the size of the lid component. The lid component is conductively connected to the ground plane but also spaced apart from the ground plane, such that there is a space between the lid component and the ground plane, and the antenna is center fed.
