Abstract:
Antenna sandwich radomes as a partial-spherical shell structure and lattice shell based on a network of triangular flat elements on the surface of a sphere are under consideration. Radiation field of such antenna covered by a radome is calculated as radiation of equivalent currents distributed over the illuminated radome surface. The Green's functions of layered radome structures are used for electric field calculation. Radiation pattern distortion occurs by the antenna radome structure and antenna location under the radome is analyzed. Lowering antenna gain, sidelobes growing and boresight errors caused by radomes are investigated. Antenna location under the radome is taken into account. Radiation properties of the reflector antenna covered by a hemispherical radome and geodesic dome made as icosahedron with various frequency of triangulation are compared. Triangular elements and hemispherical dome are fabricated as sandwich-type structure. The method has compact algorithm and is appropriate for rapid computer modelling.
