Oberflächenmontierte Antenne und Funkgerät mit einer derartigen Antenne |
摘要 |
A multi-band surface-mounted antenna (1) is formed by disposing a feeding element (3) and a non-feeding element (4) with a distance therebetween on a dielectric base member (2). The feeding element (3) is formed by extending a feeding radiation electrode (7) from a feeding terminal (5). The non-feeding element (4) is a branched element formed by branching and extending a first radiation electrode (8) and a second radiation electrode (9) of the non-feeding side from a ground terminal side (6). The single surface-mounted antenna (1) includes the three radiation electrodes (7,8,9). Thus, the antenna (1) can be easily adapted to multi-bands. In addition, the resonance waves of the three radiation electrodes (7,8,9) can be controlled mutually independently. As a result, only a frequency band selected from a plurality of required frequency bands is brought into a multi-resonance state so that the frequency band can be broadened. <IMAGE> |
