A Compact Bow-tie Shaped Wide-band Microstrip Patch Antenna for Future 5G Communication Networks

Abstract

In this paper, a novel compact bow-tie shaped microstrip patch antenna for wide-band application is presented. The proposed geometry consists of a modified bow-tie structure at the top of the Rogers RT-5880 substrate with a 50 Ω feed-line and 8 × 8 mm2 full ground plane. The diagonal slots inside the geometry have been implemented for exact resonating. The circuit analysis and various parametric analyses of the proposed geometry have been studied. The prototype of the antenna resonates at 27.77 GHz. The antenna has a fractional bandwidth of 6.77% (26.81–28.69 GHz) in simulation and 6.30% (26.89–28.64 GHz) in measurement respectively. The measured linear gain and radiation efficiency of the antenna are 7.00 dBi and 74% respectively. Also, it has a low sidelobe-level and cross-polarization level over the entire-space. The proposed wide-band antenna gives good time-domain characteristics as well as provides an acceptable FBR and impedance matching over the resonating band. All the properties suggest that the proposed antenna suits well for 5G communication along with various wireless systems.
