Abstract
n this thesis a new and exact method is presented for the synthesis and analysis of any type of hollow metallic waveguide taper. Such tapers are used in many microwave applications from satellite communication to microwave imaging. The method is based on the generalized Fourier transform pair by Pramanick and Bhartia. The method of synthesis is verified by analyzing two types of taper profiles. Those are 1) continuous profile and 2) discrete profile. For the discrete profile case, the mode matching method is used. The taper profiles examined are 1) the exponential, 2) the triangular and 3) Chebyshev. The types of rectangular waveguide tapers examined are 1) the E-plane, 2) the H-plane and 3) the EH-plane. Unlike other conventional techniques, the proposed method is exact and it does not require any computer optimization through repeated analysis which is costly in terms of computer memory and speed and needs substantial computer power. The proposed method is implemented on a personal computer since it needs an order of magnitude lower computing power. In all cases considered in this work, Chebyshev taper shows the optimum performance.
The analysis subroutines used in the thesis were verified using published experimental results on rectangular linear waveguide tapers.
