Calculation of radome-enclosed aperture antenna in 3-D
(IEEE, 2010-09)The exact mathematical model of an aperture antenna and the image theory are used to develop exact and PO integral representations of the fields radiated by radome-enclosed aperture antenna. The desired problem is reduced ... -
Effect of the off-focus shift of the feed on the radiation characteristics of a 2-D parabolic reflector antenna
(IEEE, 2010)The parabolic reflector antennas are widely used in the telecommunication systems and generally have large aperture sizes like 50λ to 80λ and larger. Their reliable full-wave analysis with the conventional Method of Moments ... -
Radiation characteristics of a 2D parabolic reflector antenna excited by the H-polarized complex source
(IEEE, 2002-09)The aim of this paper is to obtain accurate reference data for relatively large and realistic reflector antenna systems. We concentrate on a parabolic reflector antenna in the H-polarization case. The directive primary ... -
Scattering and absorption performance of a microsize graphene-based parabolic reflector in the THz range illuminated by a complex line source
(IEEE, 2017)The scattering and absorption characteristics of a two- dimensional (2-D) parabolic reflector made of graphene and placed in the free space is simulated using the Method of Analytical Regularization (MAR) technique. Reflector ... -
Smart radome improves reflector antenna directivity
(IEEE, 1997)A numerical optimization procedure is applied to two dimensional model of cylindrical reflector antenna arbitrarily located inside a circular cylindrical dielectric radome. If the radome thickness has been optimized, then ...
