High Gain Rectangular Slot Microstrip Patch Antenna for 5G mm-Wave Wireless Communication

In this Paper a rectangular shape low profile, High gain and high efficiency patch antenna with rectangular slot is presented for 30 GHz 5G wireless communication. In fact 5G wireless communication system requires a compact size, low profile and simple design structure to make sure the reliability, mobility and high efficiency. The proposed antenna is designed on a compact Rogers Substrate Rt-5880 with overall dimensions of 4. 8$\times 5\times$ 0.508 mm with relative permittivity $\varepsilon$r of 2.2 and loss tangent $\delta$ value, 0.0009. the proposed design provides a very high gain of 10 dBi at resonance frequency of 30 GHz which is one of the distinct features of the proposed Antenna The Impedance bandwidth of the proposed design ranges from 29.5-30.5 GHz which is sufficient enough spectrum for smooth flawless communication. For achieving very high gain and efficiency no any complex performance improvement techniques has been utilized like Split Ring Resonator (CRR),Electromagnetic bandgap as well as extra metamaterial involvement which itself demands some extra challenges. the antenna is more than 98% efficient. The proposed antenna is designed and optimized using commercial 3D full-wave software, viz HFSS 2018 The simulated results qualify the required standard criteria for the value of reflection coefficient |SII|$\leq$-10dB. the of radiation pattern is directional.. all these attractive Performance parameters specify the proposed design as a potential candidate for 5G wireless Communication.

I. Introduction

In association with the trend of drastic advancement in wireless networks, the currently allocated frequency spectrumhas reached its bottleneck. Millimeter waves (MMW) are anticipated as a promising solution for upcoming wireless systems. Incorporating MMW antennas will be highly instrumental which offers the advantages of miniaturization, wider bandwidth, narrow radiation beam and are well suited for enhancing the data rates with lesser delays.
