Abstract

Now-a-days, the uses of antenna based devices are rapidly increasing. Among those antenna based devices mobile phones and Wi-Fi routers are the important modules which play the crucial role in every individual’s life. As the technologies & usage of it are rapidly increasing and to meet the satisfaction of the end users all the providers are looking to elaborate their signal strength and other parameters. So, as to increase the strength of the signal the antennas should be capable of meeting it. In this paper, we would like to present the Microstrip patch antenna design of parasitic slot structure with an operating frequency of 7.5 GHZ and comparison of some their parameters with the other antenna structures. For this design, we use high frequency simulation structure (HFSS) software; the antenna is based on the FR4_epoxy substrate with tangent lass of 0.0018 and dielectric constant of 4.4(approx.). After simulation, the performance characteristics such as return loss (S11), gain, directivity, radiation pattern, VSWR are recorded and compared also.
