A Low Profile Microstrip Patch Antenna with DGS for 5G Application

A low-profile microstrip patch antenna (LMPA) with defected ground structure (DGS) for 5G applications has been developed and proposed in the paper. The antenna has a large bandwidth of 5.85 GHz that supports huge data volume. The antenna is capable of operating from 25.52 GHz to 31.37 GHz with very good scattering properties. It possesses a return loss of -35.353dB at the resonant frequency of 27.26 GHz. Rogers RT 5880 dielectric substrate having a relative permittivity of 2.2 and tangent loss of 0.0009 is used for the antenna. The volume of the antenna substrate is 20 mm×20mm×0.79mm. The gain and directivity of the patch antenna varies from 3 dB to 6 dB and 5.1 dBi to 7.9 dBi respectively within the operating frequency band ranging from 25.52 GHz to 31.37 GHz. The gain and directivity are 5.11 dB and 7.1 dBi respectively at 27.26 GHz. The VSWR over the entire bandwidth of the antenna can be presented as 1
