Structural analysis and design of microstrip antenna for S-Band applications

This paper presents the design and implementation of a Micro strip antenna which is suitable for S-Band applications. Different antennas are existed, but microstrip based patch antennas are used mostly in IC and PCB technologies which are required for the modern applications. Micro strip antenna consists of small conducting patch made of copper or gold which are placed on a dielectric material. The Microstrip antenna is fed by inset feeding technique and studies the effect of antenna dimensions length, width and the substrate parameters dielectric constant, substrate thickness on radiation parameters. The mode of operation is quasi TEM mode because the radiation is distributed in air and dielectric medium. This antenna is useful in applications over a frequency range of 2-4 GHz. The radiation characteristics are stimulated using Comsol Multiphysics 5.0 Software.
