Complementary Wideband Antenna    

Complementary antenna comprising of a planar dipole and a shorted patch antenna in electrical sense.

Overview

A combination structure comprises of a planar dipole and a shorted patch antenna in electrical sense to form a wideband antenna with unidirectional radiation pattern of various beam widths. It could be used as a basic element of the design of low cost high performance antenna arrays.

The invented wideband antenna is simple in structure and low in manufacturing costs. It has wide bandwidth, low back radiation, low cross polarization, symmetrical radiation pattern and stable in gain and radiation pattern shape over the frequency bandwidth.

Primary Application of the Technology

The antenna is excellent in all electrical parameters and attractive for development of various kinds of indoor and outdoor base station antennas for modern cellular communications. They can be mounted on walls/vehicles without affecting performance.
