Abstract (in Japanese) (See Japanese page) 
(in English) RF- and DC- line Share Ring Frequency Controllable Antenna (ShRiquen antenna) is proposed, where anti-series variable diodes pair is loaded on a ring conductor. Reactance diversity is achieved by exchanging DC voltages. Because ring roles as a DC voltage control line, DC feed circuits are not needed to be wired. In this paper, a design method is proposed to get both impedance matching and diversity effect in a wide frequency band.
