Abstract
A monopole antenna having a ground plane, a vertically extending feed line passing through a feed hole in the ground plane, a top hat in the shape of a disk connected to the feed line, the top hat being spaced from and extending over at least a portion of the ground plane, and a matching network disposed in a space between the top hat and ground plane, the matching network being arranged to effectively extend the feed hole in the ground plane. Such an antenna structure improves antenna bandwidth without increasing antenna volume or requiring external matching circuitry.
