Design and Analysis of Dual band Microstrip Antenna for Millimeter Wave Communication Applications

Abstract

Millimeter wave (MMW) communication is a key technology to enable the seamless connectivity among the various devices in the next generation wireless network (5G and beyond). However, the antenna design at MMW frequencies is a critical challenge. In this context, this paper presents a compact dual band Rectangular Microstrip Antenna (RMSA) for MMW communication applications. The design has been carried out at 33.5 GHz (Ka band) and two symmetrical slots are integrated at the optimum position to achieve the higher resonance at 62.5 GHz in the V band of MMW spectrum. The simulation results show that the antenna performs quite well and achieves the return loss of -16.6 dB and -15.03 dB and peak gain of 4.93 and 3.67 dB at 33.5 GHz and 62.53 GHz respectively. The proposed antenna design has been further extended to a dual element antenna array and analysed for improvement of different antenna parameters like gain, directivity, bandwidth and VSWR. The feasibility of the proposed antenna has been demonstrated by experimental results. The paper also presents the parametric and equivalent circuit analysis of the designed antenna
