Compact C-Slot Microstrip-Fed Planar Antenna for Wireless Devices

This paper proposes a novel, compact, multi and wide band microstrip fed planar antenna for fifth generation (5G), Wireless Local Area Network (WLAN) and Wireless Access in the Vehicular Environment (WAVE) applications. The antenna has a degree of proficiency 20x20mm

and is scripted on RT duroid Roggers substrate having a thickness of 0.8mm. The proposed antenna is consisted of rectangular radiating element where a small rectangular patch is loaded at the top of rectangular radiating element. A `C' slot is rotated in anticlockwise direction at an angle of 180° and is anchored along the Y-axis on radiating element so that the proposed antenna operates in 5G, WAVE and WLAN bands. The proposed antenna exhibits a 10 dB fractional impedance bandwidth of 10.77% (3.25} ~ 3.62) GHz and 49.71% (4.67 ~ 7.76) GHz covering a wide bandwidth requirement of 5G New Radio n77, WLAN and WAVE bands. The proposed antenna structure also confirms a good radiation performance like balloon shape polar patterns, gain larger than 2dBi and radiation efficiency greater than 80% throughout the operating frequency bands. Due to the fact that the proposed C-slot antenna has compact nature, excellent scattering and radiation characteristics, it is an attractive contender for WLAN, 5G, and WAVE operations.
