MILLIMETER-WAVE CENTER SLOT MIMO ANTENNA FOR 5G APPLICATIONS


ABSTRACT

Due to enhancement in technologies, millimeters can be used in most of the new electronic components mainly, antennas. This paper intends to design an antenna in the millimeter-wave frequency range (24GHz-300GHz) for 5G applications. Upgrading from 4G to 5G results in three main benefits: faster speed, shorter delays, and increased connectivity. Extremely fast 5G speeds mean extremely high frequency, the millimeter-wave frequency. A millimeter-wave center slot antenna with improved gain using MIMO configuration is presented. There exists valuable isolation at 28GHz. The dual-band antenna resonates at 28GHz and 45.54GHz suiting 5G applications. 


INTRODUCTION

The combination of millimeter-wave along with microstrip patch antenna is a better solution for 5G operation. Even though array structures are complex and composed of high production costs, arrays are the best solution for high gain operations. High gain structures will contravene the obstacles and lower the propagation losses. A satisfactory gain structure on FR4 substrate is proposed. This square shape antenna is not suitable for high gain 5G applications. Millimeter-wave antenna can be built upon a low loss tangent substrate which reduces microstrip line losses as well as enhances the antenna efficiency. A simple low-profile antenna delivers a single band at 59.5GHz and offers tremendous potential with greater spectrum and gain. The combination of millimeter-wave along with microstrip patch antenna is a better solution for 5G operation. Even though array structures are complex and composed of high production costs, arrays are the best solution for high gain operations. This research focuses on the early millimeter-wave frequency-28GHz, for 5G test networks as well as 5G mobile communications. For the high-frequency band, wide bandwidth is required for a high data rate. This paper proposes a MIMO 5G antenna resonating at multiple frequencies. Slots are inserted on the patch to achieve multiple band operations. The structure was simulated and analyzed using Ansoft high-frequency structure simulator version 13 (Ansoft HFSS).


EXISTING SYSTEM

  • Port MIMO Antenna 
  • Microstrip patch antenna capable of working in limited bands only 
  • Array Antenna

DISADVANTAGES

  • Need of Complex Bias Networks to reach dual-band utilization for dual-band allocation 
  • Not capable of working in mm-wave applications.
  • Less reception due to high return loss.

PROPOSED SYSTEM

In this paper, slot antenna for mm-wave 5G applications is presented. The antenna operates in dual-band of which 28GHz suits 5G requirements. The slot was analyzed and optimized. Gain has been improved with the MIMO antenna. This slot antenna is a superior candidate for 5G test networks. The antenna is designed for 28GHz which is in wide demand. Expected results such as S-parameters, antenna gain, and radiation efficiency were calculated and measured, and they can coincide with the obligations of 5G systems. 


ADVANTAGES

  • In the high-frequency band, the antenna gain will increase. Moreover, the radiated efficiency will decrease at the higher band. This may be occasioned by the reality that the directivity increases at higher frequencies. 
  • In addition, better out-of-band rejection will be achieved in the proposed design.

APPLICATIONS

    • It has good application value in modern wireless communication systems.
  • Cognitive radio systems
