Abstract
A Co-planar wave guide fed rectangular ring antenna for WiFi and 5G applications is proposed in this paper. The operating frequency of the antenna is centered at two frequencies i.e 2.52GHz and 3.65GHz which are in S-band frequency spectrum. The main radiator is rectangular ring for whose inner corners are smoothed. The similar structure of the main radiator is etched from the ground plane making the proposed technique a fractal. For the proposed antenna FR4 laminate is used as substrate and a line feed is used to provide excitation. To achieve the high wide bandwidth we have implemented the fractal technique. The antenna size is 60mm×60mm×1.6mm and is radiating in the frequency range of 2.27GHz to 2.67GHz covering 400MHz of bandwidth and 3.5GHz to 3.82GHz covering 320MHz of bandwidth.
