On the Modeling and Experimentation of Electromagnetically Coupled Microstrip Dipole Arrays in a Substrate-Superstrate
Abstract
The thrust of the research has been to develop the methodology for the modeling and design antenna arrays and microstrip discontinuities for microwave circuit applications. The thesis involves several key contributions in the subject areas of modeling microstrip discontinuities, microstrip transitions, and the synthesis of microstrip dipole arrays. This work has generated several journal publications within which one finds a fundamental contribution to the understanding of the above mentioned subjects. The analysis and the generated computer programs serve as practical tools for the design of microstrip circuits and microstrip dipole arrays. An evolution of the work has led to the understanding of microstrip discontinuity effects. In particular the theory has been extended to model microstrip bends, T-junctions, four ports, etc. In each case the algorithms account for a precise description of energy loss at discontinuities due to radiation loss and surface wave loss. These models have also been substantiated with experiment. The models are now extended to provide precise designs for microstrip corporate feeds. This will lead to the design of two dimensional transversely fed electromagnetically coupled dipole arrays. Keywords: Antenna arrays, Microstrip discontinuities, Microwave circuit Applications, Microstrip dipole arrays, Microstrip circuits.
