Abstract

This paper introduces a compact high-gain microstrip patch antenna designed to enhance bandwidth and cater to 5G applications. The antenna comprises five layers and utilizes a single-feed off-centered microstrip transmission line, operating within the 32 GHz to 40 GHz millimeter-wave band. To boost its performance, a hybrid Electromagnetic Band Gap (EBG) and Defected Ground Structure (DGS) are incorporated. The design enhancements involve the integration of two L-shaped elements on the radiating element, as well as the addition of four-square elements and two rectangular element slots at the center and edge of the ground plane. The antenna is constructed using Rogers RT Duroid 5880 as the substrate material, possessing a dielectric constant of 2.2 and a loss tangent of 0.0009, with a height of 0.254 mm. The antenna's compact structure measures 4.9 mm × 4.9 mm × 0.254 mm, equivalent to 0.92× ????g × 0.05????g. This compact size is ideal for miniaturization. Simulations were performed using Computer Simulation Technology Microwave Studio 2019 (CST MWS). The simulation results demonstrate that the proposed antenna achieves a maximum gain of 6.97 dBi and boasts a wide bandwidth spanning 7.9 GHz while maintaining a return loss of less than -10 dB. This research findings address the demand for increased gain and extended bandwidth in millimeter-wave bands, aligning perfectly with the requirements of 5G applications.
