ABSTRACT:
A low cost and multi-featured antenna is disclosed. The antenna employs a radiating element mounted to a ground plane and having first and second branches spaced above the ground plane forming a generally L shaped planar radiating structure. The antenna can be either linear or circular polarization, and can be either single band or dual band, and only one feeding port is needed to obtain circular polarization. The antenna can be easily applied to various frequency bands.
