Abstract : This research entailed the development of a unified methodology for integrated circuit, printed antenna, and printed antenna array design. Microwave antenna performance optimization may be achieved by shaping the antenna properly, as well as with the correct antenna excitation 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 will be 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.
