Mm-Wave Wideband MIMO Antenna for High Gain in 5G Generation
Abstract :
This paper analyses the designing of millimeter (MM) wave wideband with multiple input multiple output (MIMO) antenna to obtain high gain in 5G generation. The challenges of attaining better performance under varying frequency bands in MIMO antenna models are discussed and isolation methods developed for MIMO design are examined in this paper. The proposed design contains two circular patch array elements for two antennas each with a circle shaped slot to boost bandwidth. The patch antenna’s bandwidth is determined by using circle’s radius. A part of the ground plane is integrated into the antenna to achieve an operating frequency range from 24-26 GHz, at 28 GHz. To reduce mutual coupling between elements decoupling surface is used between antennas. To improve gain and to optimize bandwidth, ground plane utilizes Defected Ground Structure (DGS), partially grounded technique is used. The techniques used is compared based on S parameters and peak gain. MM wave wideband MIMO meets the desired band requirements with high gain in 5G generation.
