Design of a slotted Substrate Integrated Waveguide Antenna for 5G

As advancements in technology, it is necessary to provide fast access to users by increasing the bandwidth and data rate to achieve the data capacity available in the presently licensed spectrum. The spectrum scarcity issue may be resolved by using millimeter wave frequencies bands. In this paper, a substrate integrated waveguide antenna with a logarithmic round slot is presented. Proposed antenna is working at 38 GHz frequency for millimeter wave applications. The size of antenna is 27.06x7.50 mm2 with Rogers RT/duroid substrate height of 0.25 mm. Antenna showing gain of 7.68 dBi with efficiency of 86.82% at 38 GHz frequency. Antenna covers frequency from 38.4 GHz to 38.6 GHz with bandwidth of 0.2 GHz. A computer simulation technology tool is used to design and simulate the antenna.
