Multiband corrugated circular microstrip antenna for Long Term Evolution and 5G applications

Abstract

Multiband corrugated circular microstrip antenna is purposed for LTE and 5G applications. The antenna is designed of 150x150x1.6 mm 3 with loop feeding to reach higher bandwidth. The corrugated structure is added to advance the multiband frequency and gain performance. Variation of the structure of the Circular Microstrip Antenna (CMA) patch is analyzed. The slit, loop feeding, ring slot and corrugated slot is simulated to get the performance of return loss and radiation pattern. Impedance bandwidth in more than nine band of frequency is achieved by corrugation structure. The antenna can provides 11 dBi of directivity and can cover in the middle/high band of LTE frequency in multiband frequency.
