Description
Summary:This paper deals with analysis and optimization of wideband and ultra wideband antenna structures in the time domain by numerical solvers. In proposed method, signals at port and field probes at far-field region are used as powerful and effective markers. The method enables true time-domain computation with no susceptibility to difficulties connected with classical approach; hence is suitable especially for large structures with time-consuming analysis. Using of proposed method is demonstrated on the design of directional ultra wideband tapered slot antenna for ground penetrating radar application. Demonstration uses CST Microwave Studio.
