Pattern distortion of aperture antennas radiating in the presence of conducting platforms
Abstract
An analytically simple and numerically efficient technique for calculating the pattern distortion of aperture antennas radiating in the presence of conducting platforms located in the near or far field of the antenna is presented. The technique presented, based on the uniform geometrical theory of diffraction (UGTD), is also applicable for large aperture antennas (aperture area greater than 15 lambda-squared). An excellent agreement between the calculated and measured results obtained for a typical aperture antenna mounted on a conducting platform confirms the validity of the analytical technique developed.
