An analytical method has been developed for the scattering of high-frequency plane electromagnetic waves from a perfectly conducting strip. The solution is much simpler compared to the other methods and gives quite accurate results for ka>>1. Using Green’s Theorem, the scattering field has been expressed by an integral of the current induced on the strip. With the integral expression of Hankel function, a Fourier transform of the induced current and thus, an integral equation in spectral domain has been derived. Using some required transformation on the induced surface current, the obtained spectral equation has been reduced to its simplest form and then an approximate solution could be derived for the reduced spectral equation for ka>>1. Using this approximate solution the field related quantities such as radiation pattern and radar cross section can be obtained easily; but the induced current and current related quantities requires the numerical solution of the algebraic set of equations obtained by expressing the current in the form of an infinite series which satisfies the boundary conditions on the surface of the conducting strip.
