ANTENNA SYSTEMS COMPRISING A COMMUNICATION DEVICE, A DUAL-REFLECTOR ANTENNA AND A GRADIENT-INDEX LENS

Abstract

The present disclosure relates to an antenna system comprising: a communication device; a dual-reflector antenna; and a gradient-index lens (GRIN lens). The communication device is configured to transmit primary plane electromagnetic waves to the GRIN lens, wherein the GRIN lens is configuredto transform the transmitted primary plane electromagnetic waves to a Gaussian beam of radiation. The dual-reflector antenna is configured to transform the Gaussian beam of radiation to secondary plane electromagnetic waves and transmit the secondary plane electromagnetic waves outside the antenna system. The communication device is configured to change the direction of propagation of the transmitted secondary plane electromagnetic waves by changing the direction of propagation of the transmitted primary plane electromagnetic waves.
