CPW Fed Microstrip Antenna with U-Shaped Cut-Off and Circular Slot for Wireless Application

In this paper we have designed a CPW feed microstrip antenna with circular slot and U-shaped cut on the rectangular patch to operate at resonant frequency of 1.9 GHz. These types of antennas are of high performance, robust in design and easy to fabricate. Due to their attractive features like the transferring of the data by wireless method, its versatility and it can also be designed to any geometrical shapes and compact sizes have increased their demand very high as these are used now a days. The Patch elements used here are placed on the FR4 epoxy substrate of relative permittivity value 4.4 is kept at a height of 1.6mm from the ground. Results of simulation are the results presented by the using of HFSS version 13.0. The return loss measures -24 ��, antenna gives the impedance bandwidth of 45%, VSWR observed is 1.15 and the gain proposed is 1.55�� at centre frequency of 1.9GHz.
