Surface-mounted antenna and wireless device incorporating the same |
摘要 |
A multi-band surface-mounted antenna is formed by disposing a feeding element and a non-feeding element with a distance therebetween on a dielectric base member. The feeding element is formed by extending a feeding radiation electrode from a feeding terminal. The non-feeding element is a branched element formed by branching and extending a first radiation electrode and a second radiation electrode of the non-feeding side from a ground terminal side. The single surface-mounted antenna includes the three radiation electrodes. Thus, the antenna can be easily adapted to multi-bands. In addition, the resonance waves of the three radiation electrodes 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.
