Abstract (in Japanese) (See Japanese page) 
(in English) The antenna used for a mobile terminal or RFID is located in the vicinity of various objects such as a human body or a metallic object . In such a situation, it is well known that an antenna performance will deteriorate due to the influence of such objects. We have proposed an H-shaped antenna using parallel resonance mode by an offset feeding. It was shown that the proposed antenna has robust characteristic by numerical simulation and measurement of a prototype antenna placed on the metal plate. However we have not investigated the mechanism of the proposed antenna sufficiently. In this paper, we investigate the radiation mechanism of proposed antenna and derive the condition to have a desired radiation mode
