The characteristics of a Double-folded monopole antenna loaded by coaxial lines

Abstract (in Japanese) (See Japanese page) 
(in English) It has been shown that loading a certain reactance component at the feeding point of an antenna is useful in reducing antenna size. However, a small antenna usually has low input resistance. The approach outlined is to increase the input resistance of the small loading antenna and utilize knowledge of a folded monopole antenna. A small folded monopole antenna called the double folded monopole antenna with high resistance can then be realized. Coaxial line is also used as the loading element for the loading antenna. It is proposed that a coaxial cable DFMA can be realized by replacing the parallel transmission line loading with coaxial cable transmission line loading. All other results are provided by computer simulation using the method of moments, since results are assumed to be similar to those recorded from practical experimentation.
