Microstrip antennas consist of a very thin metallic strip (patch) on a grounded substrate found extensive applications in different fields due to their attractive features. These antennas are low profile, light weight, compact and conformable structure and easy to fabricate. These antennas have drawn attentions of scientific community over the past decades. These antennas may easily be put easily on any surface and may be easily coupled with MIC components. However their low bandwidth and gain values restrict their commercial applications. Now-a-day, the scientific community is deeply involved in improving their performance so that these may replace other antenna structures in modern communication systems.
