Application of the green’s function method for continuous line-source distribution analysis

The radiation characteristics of leaky-wave antennas located on the curvilinear cylindrical surfaces are considered. The phase distributions are shown that take into account the propagation of the wave inside the curvilinear guide structure and the spatial path of the rays from the antenna surface to the equivalent wave front. A solution is given for finding the antenna field in the far filed using the apparatus of Green’s functions.
