A High Gain Wide Band Compact Size Dual Band Patch Antenna for 5G Applications

This paper presents a high gain, compact size and dual band rectangular patch antenna for 5G applications. To enhance the gain of antenna, an equilateral triangle slots on the upper rectangular patch are constructed. The broadband antenna is operating at 27.4 GHz to 35.5 GHz and 38GHz to 41.8GHz having fractional bandwidth of 25.7% and 9% respectively. The maximum gain of 8.19 dBi is observed at 28 GHz and the antenna has radiation efficiency greater than 90% over the entire band. Moreover, the Voltage Standing Wave Ratio (VSWR) is lower than 2 dB at operational bands.
