Design of DNG Metamaterial loaded Single fed Wideband Microstrip Patch Antenna at 28GHz for Millimeter wave Applications

Abstract

Nowadays, 5G is attracting the attention of communication services because of its fast data speeds and good channel capacity. The mm-wave band, in particular the 28-GHz frequency band, is thought to present a viable option for high-quality services in 5G networks due to its low absorption rates. The single feed wideband mm-wave micro-strip patch antenna resonated at 28GHz modeled with the dimensions of 4.8 X 7.55 X 0.254 mm³ was presented in this article. In order to improve the radiation performance in terms of bandwidth, gain, and efficiency at 28GHz, a unique defective ground structure (DGS) is built with the double negative (DNG) rectangular split ring resonator (SRR) meta-material unit cell incorporated in a wide rectangular slot on a ground  plane and slots on patch. The proposed antenna structure operated in frequency band from 26.79GHz to 29.2GHz with bandwidth of 2.4GHz. The maximum gain obtained over the band is 6.04dB and the radiation efficiency is 99.9%. The results demonstrated that the proposed antenna is well suitable for 5G mm-wave Applications. The proposed antenna was designed using HFSS-19 Software.
