Abstract : Micro strip antennas are low-profile antennas. A metal patch mounted at a ground level with a di-electric material in-between constitutes a Micro strip or Patch Antenna. These are very low size antennas having low radiation. Microstrip patch antenna consists of a radiating patch on one side of a dielectric substrate (FR4) that has a ground plane (Cu) on the other side. The power transfer between a source and antenna is done through feed line. The radiating patch and the feed lines are usually photo-etched on the dielectric substrate. A good impedance matching is necessary for the power transfer between the line & patch. By providing different feeding techniques this condition of impedance matching can be fulfilled. In this paper a comparative study between inset feed, microstrip line feed, and coaxial feed is done on the basis of S11 parameter , VSWR and bandwidth using CST microwave studio software studio edition . Keywords - Microstrip Patch Antenna, Feeding Techniques, S11 Parameter & VSWR.
