Abstract

The resonant-type nonreciprocal CRLH leaky-wave antenna design provides gain and directivity enhancement, as well as lower beam squinting, compared to conventional leaky-wave antennas. However a method for complete beam-squinting elimination was not available at the moment. It is known that the beam squinting is related to dispersion of magnitude of nonreciprocity in phase constant in nonreciprocal CRLH structures. Based on the analysis of dispersion, a new approach to design of nonreciprocal metamaterial for non-squinting resonant-type leaky-wave antennas is proposed and validated experimentally.
