DESIGN AND SIMULATION OF DUAL BAND mmWAVE PATCH ARRAY ANTENNA FOR 5G COMMUNICATION SYSTEMS

Abstract

Currently, the smartphones are gaining more and more popularity, due to their increasing demand for higher bandwidth and higher data rates. The exponential growth of the population has caused telecommunication sector to meet the requirements to achieve multiband operation and improve the radio signal transmission performances. In Bhutan, 5G is expected to launch from 2022. The ongoing pandemic has made us realize the impact of better connectivity through technology. There are still some challenges that cannot be accommodated even by 4G, such as the spectrum crisis and high energy consumption. Miniaturization and multi-cell array antennas in 5G offer the possibility of high-speed data transmission but pose challenges for cell phone antenna designs.

As, it has been known that multiple-input multiple-output (MIMO) operation can effectively increase the spectrum efficiency or channel capacity, thus, the applying of MIMO technology into a smartphone will ensure the enhancement of its channel capacity. A Dual band mm Wave slotted patch array antenna for the 5G communication is proposed in this paper. The proposed antenna is operating at LTE bands 24-30GHz and 30-40 GHz. The antenna can be used in mobile phones as well as in Base stations. The bandwidth, gain, directivity, reflection coefficient and VSWR will be studied for the antenna to meet the 5G capabilities.
