The following image shows a micro-strip or patch antenna. Usually, the patch or micro-strip is choosen to be square, circular or rectangular in shape for the ease of analysis and fabrication. The radiating element and feed lines are placed by the process of photo-etching on the di-electric material. Micro strip antenna consists of a very thin metallic strip placed on a ground plane with a di-electric material in-between. Construction & Working of Micro strip Antennas ![]() The patch antennas are popular for low profile applications at frequencies above 100MHz. These are very low size antennas having low radiation. ![]() A metal patch mounted at a ground level with a di-electric material in-between constitutes a Micro strip or Patch Antenna. Micro strip antennas are low-profile antennas.
