Dual Semi Circular Disc Loaded Planar Antenna for 5G/WLAN applications

Abstract

This paper presents a monopole antenna operating at 3. 6GHz for 5G applications. The design consists of a planar monopole strip line connected to two semicircular discs on both side of the strip line. The FR4 substrate is used as dielectric material and the partial ground is used at back side. The ground plane is maintained in a $\Omega$ shaped conducting part. The antenna operates at 3. 6GHz with bandwidth of 110MHz. The antenna maintained a compact size of 28mm× 20.5mm. The antenna is suitable for narrow band 5G application at 3. 6GHz.
