Advanced Evaluation and Design Software for Antennas with Radome and FSS Structures

This proposed work envisions a software suite for modeling antennas with radomes and frequency selective surfaces. Infinite as well as finite arrays will be modeled efficiently. Phase I work will involve a feasibility study of the proposed computationalalgorithms and their capabilities for various antenna structures (periodic or finite in size) as well as structure which incorporates a radome. Nearby structures will also be considered by integration of the associated tools as they evolve. Designoptimization tools will be an integral part of the software suite and will be incorporated with the user in mind. Graphical interfaces that offer stand-alone geometry/grid generation will be developed. Additionally, the interface will allow for importingof external CAD files in standard formats as well as use of various external gridding tools. The importance of antennas to commercial and governmental organizations can hardly be overstated. They are ubiquitous structures in every military and commercialvehicle, and thus there is a continuous and growing need for antenna design methods to develop a variety of new antennas which combine a variety of competing needs. Access to capable EDA tools will become the key competitive advantage for high-technologycompanies for the next 10 to 15 years. Thus, there is an increasing emphasis on design methods for designing sophisticated multifunctional antennas.
