The Topic of microstrip antennas is an old subject that started over 40 years ago. Microstrip antennas are low profile and easily fabricated. This subject has passed through several stages that make it survive tell now and still in continues progress. The main stage is the development of low loss low cost dielectric materials that make it possible to design an effi‐ cient low profile microstrip patches. The stage of developing analysis methods and models that helped in the design of radiating.
