Design Techniques

Elliptical Micro-strip Patch Antenna (EMPA) has been emerged as a peculiar and significant category among the different shaped micro-strip patch antennas because of its circular polarization and dual-resonant frequency features with a single feed. Elliptical and its derived shapes such as semielliptical, half-elliptical, slotted-elliptical and elliptical ring are found to be particularly instrumental for bandwidth enhancement and these antennas find great applications in Ultra Wide Band (UWB) and Super Wide Band (SWB) communications. Compared to antennas with circular or rectangular shapes, the design of EMPA is a research area of high potential as there is higher flexibility in its design due to more degrees of freedom. The reported literature in the field of EMPA is very less and there is ample scope for new researchers to work on. This review paper is an attempt to summarize and critically assess the-state-of-the-art design techniques as reported in literature and understand their effects on performance of elliptical patch antenna for suggesting new research fronts in the field of EMPA.

In this paper, a broadband dual-polarized antenna with concentric rectangular ring electromagnetic bandgap (CRR-EBG) structure is proposed for 5G applications. The antenna consists of a pair of ±45° cross dipoles, an EBG array, and two inverted L-shaped improved feeding structures. In particular the ring part of the feeding structures can reduce the coupling between two ports. The leaky wave area of the EBG structure can be used to increase bandwidths. According to the measured results, the bandwidths of port1 and port2 are 32% (3.04-4.21GHz) and 28.3% (3.13-4.16GHz), respectively. The port-to-port isolation can reach up to 23 dB, and the average gain is approximately 5 dBi. The antenna has the advantages of a wide band, good isolation and a stable radiation pattern, which can be better used in 5G communications.
