  • Patent number: 7171175
    Abstract: In a method (300) for receiving a radio signal, there are steps of: receiving (301, 303) first and second received signal components by use of first and second antennas having different properties; processing (305) a received signal component to produce a sampled signal component; producing (307) at least one combined signal, which is a linear combination of at least two sampled signal components; and selecting (306) at least one set of complex values for coefficients of the linear combination so that a quality of a combined signal is at least equal to the quality of that sampled signal component having the best quality. Furthermore, the antennas are alternately connected (302, 304) via a switching element to radio frequency means so that received signal components are interleaving and so that first and second parts of a certain piece of transmitted information are received with the first and second antennas, respectively. A corresponding receiver device is also presented.

  • Patent number: 6653978
    Abstract: A device and method for receiving signals in the radio frequency range by a mobile phone. The device comprises a radiator part having a ¼ wave electric length (or an odd integral multiple thereof) for receiving the signals, wherein the feed of the radiator part is tapped for impedance matching. In order to reduce to the size of the device so that it can be implemented in a mobile phone or a communicator, the radiator part is placed at the proximity of a frame having a medium relative permittivity for dielectric loading. The relative permittivity of the frame ranges from 2 to 50 in the radio frequency range. Preferably, one or more devices are placed at one of the corners of the mobile phone body so that one device will be selected to receive the signals based on the interaction between the radiation modes of the device and the radiation field of the mobile phone body in order to achieve a right-handed, circular or elliptical polarization.

  • Patent number: 6348894
    Abstract: An RF antenna having a non-planar resonating region for radiating or receiving electromagnetic waves in order to convey communication signals between two electronic devices via a radio link. The resonating region is folded into at least two sections so that the radiating surface of one section is located on a different plane from the radiating surface of the other section. In order to optimize the input impedance of the antenna, an impedance matching part connected to the resonating region is used to provide a short circuit to the resonating region. A signal conduit part is used to feed signals to the resonating region in the proximity of the impedance matching part. Preferably, the antenna is integrated into a system connector of a hand-held communication device so as to allow the hand-held device to communicate with a communication network via a radio link.

  • Patent number: 6028567
    Abstract: The invention comprises an antenna structure particularly suitable for mobile stations operating on two frequency ranges. As a supporting component and also as component determining the electrical characteristics the antenna includes a dielectric plate (21). On one surface of the dielectric plate there is a radiating element (22) with a meander form, and on the opposite support of the dielectric plate there is a planar radiating element (23). The operation on two frequency ranges is based on the fact that the structure has two resonance frequencies, which are relatively far from each other. The strips are further relatively wide, due to which the antenna operates satisfactorily in different positions and in the vicinity of objects. The parasitic element can further have a gap operating as a separate radiator, whereby the antenna operates on three frequency ranges.
