Abstract
In this paper, radiation patterns of electrically small inverted-F antennas(IFAs) on an electrically large cylindrical conducting body like a satellite launcher are experimentally studied. First, radiation patterns are obtained by using method of moment and a commercial software tool, HFSS(High Frequency Structure Simulator) and the results are compared and analyzed with experimental ones. Especially, when the size of a cylindrical conducting body is electrically large, the effects of the size of a cylindrical conducting body on radiation patterns are studied by considering only the partial ground in vicinity of antennas. And then, when one and two inverted-F antennas are on the cylindrical conducting body, radiation patterns are simulated and investigated by using method of moment and HFSS. Good agreements are observed among the results by method of moment, HFSS, and experiments.
