Performance Analysis of a Novel High Impedance Surface for Microstrip-line Small Patch Antenna for Mobile Applications

This paper is concerned with the design and manufacture of 4G patch antenna with the newly introduced artificial materials known as artificial magnetic surfaces or high impedance surface (HIS). The use of HIS for antenna performance enhancement is growing at a rapid pace. In this article a modified form of HIS is presented and successfully integrated with antenna for improved performance under low profile limitation. Frequency of operation is taken to be The industrial, scientific and medical (ISM) ISM 5.8 GHz and antenna parameters which are compared here are: Reflection Coefficient S11(dB), Radiation Pattern, Gain, Directivity and Bandwidth. Considerable amounts of improvements have been noticed with the use of HIS.
