Abstract

A method has been developed to compute the resonant frequency of a rectangular microstrip antenna immersed in a linear isotropic plasma medium using Wolf's dynamic dielectric constant model. The results obtained are in agreement with those obtained using spectral domain technique. It has been observed that the antenna resonates at a higher frequency inside the plasma than in free space.
