摘要：Microstrip patch antenna has some drawbacks of low efficiency, narrow band (<5%), and surface wave losses. In this paper it is shown that we can increase the resonant frequency by decreasing the value of dielectric constant of dielelctric substrate without changing any other parameter. here we have taken the substrate value as 11.8 ,9.8 ,6.8 and 4.8.we have taken 1.5 mm as a substrate height. the simulated results for rectangular microstrip patch antenna are given with the help of feko software for verifying our results.
