Simulation of a Broadband Antenna with the Method of Moments
MetadataZobrazit celý záznam
In the paper selected problems of computer simulations of a broadband antenna containing large metallic surfaces with the Method of Moments have been discussed. A novel broadband combined spiral-discone antenna, built of a complementary spiral and a cone has been analyzed. Since the antenna contains large metallic surfaces wire-grid models had to be developed in order to simulate the antenna with the thin-wire kernel method of moments. Several wire-grid models of the antenna have been proposed and analyzed. The simulation results for input impedance have been compared to those obtained from measurements and the best model of the antenna has been identified.
