Millimeter Wave Wideband Patch Antenna with DGS Slots and Truncated Corners for 5G Applications

Progress In Electromagnetics Research C, Vol. 167, 149-154, 2026
Abstract
This paper presents the design, simulation, fabrication and experimental validation of a compact millimeter-wave microstrip patch antenna intended for fifth-generation (5G) wireless applications. The proposed antenna employs a coplanar waveguide (CPW) feed, a defected ground structure (DGS), and truncated patch corners to enhance impedance bandwidth and radiation characteristics while maintaining a compact footprint. The antenna is designed on a Rogers RT/Duroid 5880 substrate (εr = 2.2, tanδ = 0.0009, thickness = 0.502 mm) and operates in the Ka-band with a center frequency of 30 GHz. Measured results demonstrate an impedance bandwidth from 29 to 34 GHz and a peak realized gain of 7 dBi, showing good agreement with simulated predictions. These results indicate that the proposed antenna is a suitable candidate for compact 5G millimeter-wave communication systems.
