ABSTRACT:
Disclosed is a non-stationary antenna whose characteristics are guaranteed free of the surrounding variables, such as configuration of the land, electrically conductive condition of the earth's surface, buildings of different heights or climatic changes. The non-stationary antenna has upper and lower antenna conductors decoupled by the capacitors of a resonator arrangement. Thus, if the surrounding variables should cause an adverse effect on the upper antenna conductor, it cannot be transmitted to the lower antenna conductor. Also, the antenna can be bent, and can be held in the bending position until it is straightend with hands. Thus, no matter what posture an associated wireless may take, the antenna can be bent so as to take a vertical posture, which is most appropriate for radiating or receiving electromagnetic waves.
