Abstract

A triple-band microstrip antenna based on the DGS technology is proposed with the enhancement of gain as well as improvement in bandwidth. Split Ring Resonator (SRR) is accomplished in the bottom plane which is working as a stop band in operating bandwidth. Two rectangular radiators are placed in series, where two symmetrical inverted L-shaped slots are responsible for bandwidth enhancement of the antenna. The 10 dB impedance bandwidth (IBW) of the antenna is 3.22 GHz to 3.35 GHz, 3.48 GHz to 3.58 GHz and 4.45 GHz to 4.59 GHz which can be used for 5G communication applications. The gain improvement is achieved in all operating bands and 5.2 dB maximum gain is observed at 3.23 GHz with 3.2 dB gain enhancement.
