摘要

A novel, compact, variable-notch omnidirectional antenna is presented.The antenna has a compact size of 22.5 mm (0.3?) X 22.5 mm (0.3?) X 1 mm and made on cheap FR4 with relative permittivity of 4.4 and dielectric loss tangent of 0.02. It has a stable omnidirectional pattern all over its operating frequencies and a satisfactory gain. Antenna geometry consists of a T-shape cut in the patch plane and an inverse T-shape parasitic element.
