MIMO Antenna for C-band Applications

Abstract

Two elements of MIMO antenna for WLAN, IoT, and satellite applications are anticipated and scrutinized. The proposed antenna is comprised of a rectangular ring with two curved patches and is fed by a feed line. This miniaturized antenna has an area of $15\times 20\ \text{mm}^{2}$ that can function at 6.14 GHz with a return loss of -10 dB. The resonance at 6.14 GHz is obtained by introducing two curves in a rectangular ring with concave surfaces. Antenna gain at resonance frequency is 5.4 dBi. It has an omnidirectional pattern in terms of H-Plane and a dipole pattern in terms of E-Plane as well as acquiring stable gain while using a partial ground plane. The antenna is successfully stimulated with a maximum ECC value of 0.02 and a diversity gain of 9.98 dB.
