A MM-wave circularly polarized substrate lens antenna for wireless communications

Abstract

As the need for wireless systems with wider bandwidths is growing, the microwave frequency band either becomes too congested or simply cannot support the ever increasing data-rate requirements. Therefore, the operating frequency of wireless communications systems is gradually shifting towards millimeter-wave frequencies [1], resulting in an increased interest in recent years in developing millimeter-wave (mm-wave) integrated circuit (IC) antennas for indoor and outdoor wireless communications.
