Abstract

A description is given of a method of designing phase- correcting Fresnel zone plate lens antennas for operation at two or more frequency bands. A new analysis is derived for apportioning the amount of phase correction to give the desired performance at the chosen frequencies. The result permits the development of narrow-beam, high-gain behavior at two or more bands, with reduced gain at other frequencies.
