| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | A novel wideband monopole antenna for a mobile terminal with a slide structure is proposed, and this antenna uses the resonance of the slide structure. The slide structure has two ground planes which overlap each other, and the upper and lower ground planes are connected by FPC (Flexible Printed Circuit). Since the slide structure can be treated as a shunt resonator, a kink appears in the input impedance of the antenna, and the wideband characteristic is obtained. The resonance frequency of the slide structure can be adjusted by changing the length of FPC and the capacitance between the upper and lower ground planes. This is verified by FDTD simulations and measurements. Also, above the resonance frequency of the slide structure, since the current distribution changes considerably and the conductor loss increases, the radiation efficiency decreaeses. | |
