An Omni-directional Rectangular Patch Antenna for 5G/WiFi/WiMAX Applications

This paper represents an omni-directional rectangular patch antenna for lower 5G/WiFi/WiMAX applications. The antenna is simulated by using CST v. 2018. The antenna is mounted on Rogers RT 5880 with thickness of 0.79mm, relative permittivity of 2.2, thermal conductivity of 0.2 [WK/m], loss tangent (tan$\delta$) of 0.0009. The dimension of the antenna is $36 \times 31 \times 0.79$ mm

. It operates with a huge bandwidth of 3259.3 MHz, which exhibits the operating frequency range from 2.9971 GHz to 6.2564 GHz. The gain and the directivity are 3.011 dB and 3.499dBi at 4.08 GHz. The antenna shows VSWR of 1.041, average radiation efficiency of $\approx$ 93.2% throughout the entire band. Considering all the characteristics, it can be regarded as a suitable candidate for lower 5G/WiFi/WiMAX applications.
