A switching function and multiband compatibility and a function handling deviation of matching caused by the influence of the human body are configured in a single matching circuit. An antenna matching circuit is formed by a reactance changing section and a matching section. The matching section is formed by a parallel circuit of an inductor and a capacitor, and the LC parallel circuit is shunt-connected between a feed section and the ground. The reactance changing section changes the resonant frequency to be compatible with a plurality of bands, and performs fine adjustment of the resonant frequency changed by the influence of the human body. The parallel inductor causes the locus of input impedance of the antenna matching circuit to draw a small circle locus in the first quadrant of a Smith chart. The parallel capacitor is adjustable to move the small circle locus to the center on the Smith chart.

Принадлежит: Heikki Korva, Zlatoljub Milosavljevic

An adjustable multiband antenna especially intended to mobile terminals. The antenna structure comprises a radiator ( 320 ), a feed element ( 330 ) and an adjusting circuit ( 350 ). The radiator is a conductive part of the outer cover (COV) of a radio device or conductive coating of the cover. It is fed electromagnetically by a feed element which is isolated from the radiator by a relatively thin dielectric substrate. The feed element is connected either directly or through an intermediate element ( 340 ) to the antenna port of the device and to the ground plane ( 310 ), and it is shaped so that the antenna has at least two operating bands. The adjusting circuit is connected to an adjusting point (AP) in the feed element, and the reactance between the adjusting point and ground and thus the electric size of the antenna can be changed by means of a switch (SW) in the adjusting circuit. Among other things, the component values of the adjusting circuit and the distance between the short-circuit (SP) and adjusting (AP) points in the feed element are variables from the point of view of the antenna adjustment. Displacements, which have desired directions and lengths, are obtained for at least two operation bands of the antenna independently from each other by changing the switch state. The efficiency of the antenna is better than of the corresponding known antennas, and its matching can be made good both in lower and upper operating band of the antenna.

An internal dual band antenna meant for small radio devices. In one embodiment, the antenna contains two radiators and a parasite element, which is shared between them. The parasite element is implemented on three sides of the antenna module, which are perpendicular to the side where the two radiators are implemented. The short-circuit conductor of the parasite element extends close to the supply point/points of the antenna on the circuit board of the radio device and is connected to the ground plane of the radio device. The antenna structure is dimensioned such that the two resonance frequencies on both functional bands are at a lower frequency than the resonance frequencies of the actual radiators. Accordingly, both the lower and upper frequency band is widened. The shape of the parasite element does not weaken the adaptation of the antenna in either functional band.

The antenna can be located at the back surface of the battery or the rear surface of a wireless phone, facing away from the user. An RF shielding device can be embedded into the battery and configured in relation to the antenna such that the RF field intensity and the consequent specific absorption rate for the user is lowered while the outgoing signals of the wireless device remain fully adequate for the function of the wireless device. This feature is preserved for a multi-band operation because a digital phase shifter is used between two radiating antennae. An external case is used as a complement to the wireless phone.

In an antenna device, first linear portions of a coil conductor are located on a lower surface of a first resin sheet. Second linear portions of the coil conductor are located on an upper surface of a second resin sheet. Via conductors of the coil conductor are formed in the first and second resin sheets and intermediate resin sheets located between the first and second resin sheets. The via conductors connect a first end and a second end of the first linear portions and a first end and a second end of the second linear portions, respectively. The first and second linear portions and the via conductors define the coil conductor. Each of the intermediate resin sheets includes an aperture in the center portion thereof. The lamination of the apertures defines a cavity in which a magnetic substance core is embedded. The coil conductor is wound around a periphery of the cavity.
