| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In recent years, the demand for tunable antennas has been increasing with the rapid growing various wireless communication systems. In conventional works, the co-design approach of tunable bandpass filter and tunable antenna have been proposed to realize a variable frequency characteristic with a constant absolute bandwidth. However, such tunable filtering antennas have two main problems: 1) variable frequency range is narrow and 2) the beam width is wide because there is no beam-forming function. This paper proposes a new tunable filtering array antenna that can form a directional beam using a two-element array and has a wider variable frequency range than conventional tunable filtering antenna. As an example, we design a microstrip tunable filtering array antenna with a tunable range of 2.32-3.12 GHz (29.4%) and 150-MHz constant equiripple bandwidth. The effectiveness of the proposed tunable filtering array antenna is verified through the comparison of frequency-selective/tunable and radiation characteristics between EM simulated and measured results. | |
