High Gain and Low Return-Loss Dual-Band DGS Antenna Loaded with Stub-Slot Configuration for 5G Wireless Communication

In this paper, A dual-band Defected Ground Structured (DGS), stub-slot configuration antenna is proposed for the 5G mid-band and upper unlicensed frequency region. High sensing gain, bandwidth, and stable radiation pattern are achieved by the proposed antenna that are the basic requirements of IoT applications that are available in 5G. The resonant frequency of this antenna is 3.532 GHz and 6.835 GHz where high realize gain, bandwidth and efficiency are 5.26 dB, 4.35 dB, 8.16%, 6.1% and 99.99%,85% respectively. The overall size of the antenna is 33.5x33.5x1.59. The Rogers RT/Duriod 6202 substrate material is used as a substrate.
