摘要： An antenna includes a first radiating element (2a), a second radiating element (2b), a third radiating element (2c), a first switch element (7-1) for switching an electrical connection between the first radiating element (2a) and the second radiating element (2b), a second switch element (7-2) for switching an electrical connection between the second radiating element (2b) and the third radiating element (2c). The first radiating element (2a), the second radiating element (2b) and the third radiating element (2c) are conductor patterns formed on a dielectric member (1) that is separate from a printed circuit board (4) and has a dielectric constant larger than that of the printed circuit board (4).

摘要： A printed circuit board has an inverted-L-shaped antenna pattern, which is provided with a conductor pattern connected to a ground pattern, so formed thereon as to be in close proximity to the outside of an inverted-F-shaped antenna pattern which is provided with a conductor pattern connected to a feeding point and with a conductor pattern connected to a ground pattern. By making resonance frequency of each of the inverted-F-shaped antenna pattern and the inverted-L-shaped antenna pattern different, it is possible to compose a frequency antenna using different frequency bands.

摘要： A ground pattern 8 has a portion thereof removed in an area 13 where an inverted-F plate antenna 1 is mounted. This gives the inverted-F plate antenna 1 almost non-directional directivity patterns as distinct from those obtained with an ordinary inverted-F antenna, and helps achieve a higher degree of gain isotropy.

摘要： An antenna device of the present invention includes a radiating element and a matching circuit connected to the radiating element and provided with capacitance elements. In the antenna device, a PIN diode is employed as one of the capacitance elements, and the capacitance of the PIN diode is controlled such that a resonant frequency is controlled. Thus, it is possible not only to simply the matching circuit and reduce the size thereof with ease but also to shift the resonant frequency with a relatively low voltage. This makes it easy to prevent as much as possible a decrease in radiation efficiency.
