V BAND FREQUENCY RECONFIGURABLE ANTENNA FOR MILLIMETER WAVE APPLICATIONS

Abstract

A compact V band frequency reconfigurable microstrip patch antenna is introduced in this paper. The introduced antenna is a Psi shaped patch designed to operate at 48 GHz. This basic structure is modified by introducing p-i-n diodes, radiating slots, and resistors on the surface of the patch which exhibits multi-band operation at 63 GHz, 68 GHz, 69 GHz, and 70 GHz and is well suitable for 5G applications. The compactness of the introduced antenna is 8 mm×8 mm×0.254 mm and operates at the millimeter-wave range, i.e., (30 GHz - 300 GHz). The two p-i-n diodes are arranged on either side of the feeder and two symmetric slots with resistors are placed on the substrate which controls the feed line and this structure achieves the frequency reconfigurability. The patch is made of copper material and the antenna is designed on a material known as ROGERS R03003 substrate with properties of ε = 3 and δ = 0.0013 and due to the dielectric loss for high-frequency performance, used an EM simulator which is HFSSv16. The simulated results show optimum gain and wide bandwidth at the operating frequency.
