FDTD analysis of microstrip patch antenna covered by plasma sheath

In this paper, a microstrip inset-fed patch antenna covered by plasma sheath is simulated by using the (FD)2TD algorithm. Expressions of calculating the coefficients in the electric field update equation for cold plasma are presented in detail. Computational examples illustrate that the resonant frequency of the patch antenna covered by plasma sheath is changed. The curves presented in this paper may be useful when introducing appropriate corrections in the design of the microstrip patch antennas in the plasma environment.
