Abstract (in Japanese) (See Japanese page) 
(in English) For the purpose of developing compact and thin antennas at UHF-band, a monopole array antenna consisting of a folded J-shaped λ/4 monopole antennas was devised. And, matching circuits such as an open-ended slotted line stub and a high impedance step section were installed to improve the antenna performance. In this paper, to clarify the physical meaning of the matching circuits, a radiation characteristic of the slotted line stub was calculated by using the electromagnetic simulator, and besides, an equivalent circuit of the antenna and matching circuits was considered. According to this result, agreement between the network theory and the full-wave analysis is reasonably satisfactory, and hence the validity of the matching circuit.
