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.

摘要： Power non-supplied side radiation electrode 3 and power supplied side radiation electrode 4 are formed on the surface of a dielectric substrate 2 with a space therebetween. A permittivity adjusting material portion 8 is provided in the space S which is situated between the power non-supplied side radiation electrode 3 and the power supplied side radiation electrode 4, and in which a capacity occurs. The permittivity adjusting material portion 8 has a lower permittivity than that of the dielectric substrate 2, which causes the permittivity between the power non-supplied side radiation electrode 3 and the power supplied side radiation electrode 4 to be lower than that of dielectric substrate 2, and weaken the capacitive coupling between the power non-supplied side radiation electrode 3 and the power supplied side radiation electrode 4.

摘要： A first radiating electrode 5 and radiating electrode 6 are formed on an upper face 2c of a dielectric base 2 of a surface-mounted antenna 1, and a rectifying circuit 7 is formed on a side face 2b where radiating electrodes 5 and 6 are not formed. This facilitates configuration of a desired rectifying circuit 7 appropriate for the surface-mounted antenna 1, and rectification of the surface-mounted antenna 1 is facilitated. Also, since the rectifying circuit 7 is formed on the side face 2b of the dielectric base 2, effects of the rectifying circuit 7 on the first radiating electrode 5 and second radiating electrode 6 on the upper face 2c can be reduced. Accordingly, high gain and increased bandwidth of the surface-mounted antenna can be obtained.

摘要： An antenna device includes a base including a planar conductor disposed thereon, and a coil antenna. The coil antenna includes a coil conductor wound around a magnetic core. The coil antenna is arranged such that a coil opening of the coil conductor is closed to an edge of the planar conductor. A current passing through the coil conductor induces a current in the planar conductor. Thus, a first magnetic flux occurs in the coil antenna, and a second magnetic flux occurs in the planar conductor. Therefore, a third magnetic flux occurs in an area of the planar conductor. Accordingly, the antenna device achieves a small footprint, a small-sized communication terminal apparatus and a desired communication distance.
