Compact F-Shaped Antenna with its Analytical Modelling Resonating at 3.5 GHz for 5G Applications

Abstract

A defected ground structure-based F-shaped patch antenna with LC analytical modelling is presented in this work. The proposed DGS antenna is working between 3.4 -3.6 GHz over -10 dB impedance bandwidth. Realizing the antenna into an open-ended slot is etched on the ground plane thereby improving the impedance matching. The proposed antenna is printed on the 0.8mm thick FR4 substrate by occupying overall area around 19.3 x 6.2 mm2. The effect of slot in the ground plane is analyzed with the help of equivalent circuit. The prototype of the proposed antenna is manufactured and tested. The antenna shows better performance in both measured and simulated results.
