Abstract

An omni-directional circularly polarized (OCP) antenna operating at 28GHz is reported and has been found to be a promising candidate for Device-to-Device (D2D) communications in the next generation (5G) wireless systems. The OCP radiation is realized by systematically integrating electric and magnetic dipole elements into a compact disc-shaped configuration (9.23 mm³ = 0.0076 λ30 at 28 GHz) in such a manner that they are oriented in parallel and radiate with the proper phase difference. The entire antenna structure was printed on a single piece of dielectric substrate using standard PCB manufacturing technologies and, hence, is amenable to mass production. A prototype OCP was fabricated on RogersTM 5880 substrate and was tested. The measured results are in good agreement with their simulated values and confirm the reported design concepts. Good OCP radiation patterns were produced with a measured peak realized RHCP gain of 2.2 dBic. The measured OCP overlapped impedance & AR bandwidth was 2.2 GHz, from 26.5 to 28.7 GHz, an 8.0% fractional bandwidth, which completely covers the 27.5 to 28.35 GHz band proposed for 5G cellular systems.
