A wideband probe-fed low cost mm wave fractal antenna array for 5G

Abstract

Antennas for 5G needs to be compact, low-cost and of broad band. The proposed antenna is a co-axial fed Sierpinski fractal antenna of 1stiteration which satisfies most of the important requirements for prospective 5G cellular communication. The proposed design has broad impedance bandwidth of 2.6 GHz at resonant frequency of 28.2 GHz and suitable radiation pattern for beam steering. Various characterization studies are performed to achieve beam steering. An L-shaped array of the proposed antenna is designed for this purpose. This array is also placed on a generic smartphone mock-up and the radiation pattern is characterized.

PSOGSA for the Design of Hybrid Fractal Curve Based MIMO Antenna for 5G Applications

“…HFA using Sierpinski Carpet and Minkowski fractal is designed by Sharma et al [34] for applications like C-band, Wi-MAX, hi speed point to point wireless communication and X-band. By using above mentioned fractal and hybrid fractal geometries numerous types of fractal antennas are designed which are suitable for 5G communications [35][36][37][38][39][40][41][42][43][44][45]. MIMO antennas are proficient candidate of integrally justifying the properties of network quantity, multipath, producing a best-quality dependability of the link, channel volume, gain exposure without challenging more impedance bandwidth for additional enlightening the quantity and spectrum effectiveness of MIMO antennas and the massive MIMO emanated into presence, somewhat a development of MIMO is essentially clustering the antennas together at the receiver as well as transmitter.…”

Comparative analysis of hybrid fractal antennas: A review

“…The distinct fractal geometries have been used by the researchers to design the antenna useful for 5G applications. [46][47][48][49][50][51][52][53][54][55][56] MIMO antennas are capable of inherently mitigating the effects of multipath, network throughput, causing a better-quality link reliability, gain, channel capacity, coverage without requiring additional bandwidth, and diversity performance because of spatial (or signaling) degree of freedom. For further improving the throughput and spectrum efficiency of MIMO antennas, the massive MIMO came into existence, rather it is an expansion of MIMO which basically groups together antennas at the transmitter and receiver.…”
