Microstrip antennas are inherently narrow band devices with low efficiency. On the other hand, they have many unique and attractive properties they are low in profile, light in weight, compact and conformable in structure, and easy to fabricate and to be integrated with solid-state devices. They are superior to the conventional flush-mount antennas since they are truly thin antennas, requiring no cavity backing. There seems to be little doubt that they will find more and more applications as more compact efficient solid state sources, amplifiers, and self-matching networks are developed to compensate for the shortcomings. In this investigation a simple and useful theory, based on the cavity model, has been developed to analyze and predict the fundamental behavior of microstrip antennas of various basic shapes. In general, there is a good agreement between the theory and experiment.
