Analysis of Rectangular Micro Strip Antenna

Micro strip antennas now a days had a wide application but unless analysis and optimization for rectangular micro strip antenna is made it is not possible to get high end performance from them. Several methods are there for to calculate the resonant frequency of a microstrip antenna using rectangular cavity models. The analysis which is done based on the model of the cavity, introduces the concept of dynamic permittivity taking into account effects of edges of fields. Final results with dynamic permittivity model gives better achievements compared with the experimental measurements.
