Abstract

A conductor-backed coplanar waveguide(CB-CPW) fed elliptical patch-slotted antenna for 5G applications is presented in this paper. The defected ground structure proposed in the design with an area of 16.5mm ×5mm makes the antenna more efficient. Also, an improved impedance matching is achieved by directly coupling the CPW feed line to the patch. CPW, semi-circular background, dielectric, and transmission line are the different layers of the antenna, and FR-4 epoxy with ϵr= 4.4 and loss tangent= 0.02 is used as dielectric. The size of the designed CPW-fed antenna is only 40×40×1mm3. A bandwidth of 3GHz (4.5GHz-7.5GHz), which covers the 5G band, and a maximum gain of 4.46dB was obtained.
