A Compact multiband patch antenna for 5G applications using rectangular slotted DGS

Abstract

The main purpose of the dealt design was to realize the frequencies used for the upcoming 5G technology. The dual band antenna of $10 \times 10 \times 1.6\ \text{mm}3$ size producing the frequencies 10.5 GHz and 26.9GHz with a S11 of −25.98 decibel and −26.07 decibel correspondingly. The dielectric material used is FR4 epoxy having 4.4 as its permittivity. It has a quadrilateral slot in the ground to achieve better bandwidth. The VSWR obtained for the generated frequencies is 1.1057 and 1.1046. The examination of return loss, radiation pattern and gain were finished utilizing High Frequency Structured Simulation instrument.
