Compact magneto-dielectric resonator MIMO antenna for angle diversity

Abstract

This paper presents a two-element MIMO antenna configuration designed using magneto-dielectric (MD) material. The MD material has been designed such that its temperature coefficient value approaches zero. The microwave dielectric constant and permeability of the material is calculated by Nicholson-Ross-Weir conversion technique and found to be 8.02 and 1.64, respectively. Each element is designed so that it can operate at 5.71 GHz. The two elements of the MIMO configuration are separated by quarter wavelength and half wavelength and are compared. The designed antenna can give a quad-directional radiation property, which can be utilized for the diversity scheme.

“…To meet such demands, magneto-dielectric resonator antennas (MDRAs) have been broadly used. 1,2 The MDRAs have magnetic and dielectric properties such as low losses, wide bandwidth, and frequency stability (even under temperature variation). These antennas can be easily excited with small dimensions for high frequency and microwave band applications.…”

“…In the design of portable systems, the wish of gradually shrinking dimensions is a challenge faced by the antennas' designers in continuously search for miniaturized wireless devices. To meet such demands, magneto‐dielectric resonator antennas (MDRAs) have been broadly used 1,2 . The MDRAs have magnetic and dielectric properties such as low losses, wide bandwidth, and frequency stability (even under temperature variation).…”
