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

Abstract

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.
