Abstract

A simplified short backfire directional antenna provides both sum and error adiation patterns in the H-plane. Three parallel dipoles are mounted above a pan-type reflector, with a small metal reflector disc over the dipoles. The center dipole is excited to produce a sum pattern and the two end dipoles are excited out of phase to provide an error pattern with a broadside null in the H-plane. Alternatively, a hybrid circuit may be used with a pair of parallel dipoles to generate the desired patterns. Improved gain and resolution are achieved with a small antenna array.
