“…Nowadays compact antenna structure is essential requirement for modern wireless systems. The use of magneto‐dielectric resonator antennas (MDRAs) gained huge attention from the researchers all over the world due to their attractive advantages and properties such as compact size, broad bandwidth, and high‐radiation efficiency . The size miniaturization of antenna can be achieved using dielectric materials , however, increase in the permittivity causes reduction in the frequency bandwidth of antenna leading to limitations in size reduction and trade off in performances.…”

This article presents quad‐directional magneto‐dielectric (MD) resonator antenna configuration, designed using two different MD materials with stack configuration. These materials have been designed such that their temperature coefficient is approximately zero. The microwave dielectric constant (εr) and permeability (μr) of both materials are calculated by Nicholson–Ross–Weir conversion technique and found to be 8.02, 1.64 and 10.47, 1.52, respectively. The designed antenna can radiates in four directions simultaneously at the resonant frequency of 5.84 GHz. The beam shaping has been achieved using single feed and this property can be utilized for the angle diversity. © 2016 Wiley Periodicals, Inc. Microwave Opt Technol Lett 58:62–64, 2016

Abstract-Structural, vibrational and microwave dielectric properties of Nickel-Copper-Zinc ferrite (Ni 0.2 Cu x Zn 0.8−x Fe 2 O 4 ) ceramics have been presented in this paper. Samples have been prepared using conventional auto-combustion method. The X-ray diffraction (XRD) results confirmed the ferrite samples to be of cubic spinel structure, which further was validated by Fourier transform infrared (FT-IR) and Raman spectroscopy. The relative permittivity (ε r ) increased from 7.474 to 8.132 with successive increase in Cu content. The observed and calculated permittivity using ClausiusMossoitti relation have been in good agreement. The temperature coefficient of resonant frequency (τ f ) decreased from −75.85 ppm/ • C to −32.12 ppm/ • C with increase in successive Cu content. The relative permeability (µ r ) have been calculated by using the Nicholson-Ross-Weir conversion technique. Using Ni 0.2 Cu 0.2 Zn 0.6 Fe 2 O 4 sample the ferrite resonator antennas have been designed in three different shapes. The experimental and theoretical characteristics of the antennas have been compared and a good agreement has been achieved.

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.
