A SURVEY OF TECHNIQUES AND DESIGN FOR MICROSTRIP PATCH ANTENNA

Mrs. Kamini U. Gaikawad, Mrs. Rashmi P. Belokar

In todayâ€™s growing world, Microstrip also known as patch antennas are becoming more useful as they can be printed openly onto a circuit board. The Microstrip antennas are also very useful within the mobile phone market. Patch antennas are low profile, low cost and are easily fabricated. In telecommunication, there are several types of microstrip antennas and the frequently used is the patch antenna or microstrip patch antenna. Microstrip antennas are relatively economical to design and assemble because of feature like simple 2-dimensional physical geometry. They are usually employed at UHF and higher frequencies because the size of the antenna is directly tied to the wavelength at the resonant frequency. A single patch antenna has ability to provide maximum directive gain of around 6-9dBi. It is relatively easy to print an array of patches. Patch arrays can gives greater gains at little additional cost; matching and phase adjustment is possible to perform with printed microstrip feed structures, again in the same operations that form the radiating patches. The patch antenna has is able to create high gain arrays in a low-profile which make it applicable on airplanes as well as in other military applications.
