Abstract

In this work, a novel wideband and low-profile discrete dielectric lens (DDL) antenna is presented. The proposed unit cells of DDL with square-pyramid structure can realize wideband anti-reflection (AR) at an air-dielectric interface. By increasing the phase compensation range, the DDL antenna with very large gain bandwidth but large DDL thickness would be achieved. Furtherly, based on the large gain bandwidth technology, a novel multi-folded lens structure is proposed to realize low profile design, in which a broadband polarization rotation reflection surface (PRRS) is proposed, while a polarized grid is used appropriately. Finally, the proposed multi-folded DDL antenna can achieve a very large gain bandwidth, while the thicknesses of the DDL unit cell and the total antenna can be greatly reduced. For demonstration, the proposed multi-folded DDL antenna is fabricated and measured. The fabrication was implemented by using a simple and low-cost three-dimensional (3-D) printing technology. The results show that the proposed lens antenna can realize a 1 dB gain drop bandwidth of 43%, thickness of less than 1/3 focal-length-to-diameter ratio, and maximum aperture efficiency of 32%. Good agreement can be observed between the measurement and simulation.
