Unified Methodology for Integrated Circuit Printed Antenna Array Design

摘要

This research entailed the development of a unified methodology for integratedcircuit, printed antenna, and printed antenna array design. This final report presents a methodology for the design of 3-D microstrip-fed, arbitrarily-shaped aperture and patch antennas in a multilayered medium. It includes the design of antenna excitation either through parasitic coupling, or through a via hole transition from a microstrip line. Comparison of numerical results with experimental data shows good agreement. A methodology for the design of multiple via hole and air bridge transitions of arbitrary shape in multilayered multiport microstrip circuits is also presented. Application of multiple via holes to the design of microstrip filters and other devices is discussed. To properly describe the current along the vertical post, the simple pulse function with triangular cross section is used in the moment method analysis. Circularly and rectangularly shaped vertical transitions are analyzed for several practical applications. Comparisons of numerical results with experimental and available data again shows good agreement.
