These Microstrip antennas are used in spacecraft, aircraft and some low profile applications. The Advantages of Microstrip antenna are lighter weight, low cost, and ease of installation, while the disadvantages are inefficient radiation and narrow frequency bandwidth. To have a greater directivity, an array can be formed using these patch antennas. It has low radiation power and narrow frequency bandwidth. The radiation pattern of the microstrip patch antenna is broad. Provide a physical and mathematical basis for understanding how microstrip antennas work. Concise and readable, it provides theoretical background, application. Provide an introduction to microstrip antennas. When the antenna is excited, the waves generated within the di-electric undergo reflections and the energy is radiated from the edges of the metal patch which is very low. Antenna Theory and Microstrip Antennas offers a uniquely balanced analysis of antenna fundamentals and microstrip antennas. The length of the metal patch should be λ/2. The patch is generally made of conducting material such as copper or gold and can take any possible shape. In its most basic form, a microstrip patch antenna consists of a radiating patch on one side of a dielectric substrate which has a ground plane on the other side as shown in figure 3.1 1. The above shown is the image of a microstrip patch antenna. THEORY OF MICROSTRIP PATCH ANTENNA 3.1 Basic Structure. Usually, the patch or microstrip is chosen 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 dielectric material.

The microstrip consists of a very thin metallic strip placed on a ground plane with a dielectric material in-between.

The patch antennas are popular for low profile applications at frequencies above 100MHz.

These are very low size antennas having low radiation.
