Analysis of the Asymmetric Dual Reflector Antenna Systems by Using Equivalent Feed and Antenna Concepts

In this study the equivalent paraboloid model is formulated and applied for dual asymmetric antennas that can give the same scattered fields as in dual symmetric antenna systems. This type of modeling leads to the application of Physical Optics (PO) and Geometric Theory of Diffraction (GTD) analysis for finding the radiation pattern of off-focus fed asymmetrical dual reflector antenna systems.
