    摘要： An antenna transducer, and an associated method, for a mobile station operable in a cellular communication system. The mobile station also includes GPS receive circuitry for receiving and operating upon GPS (global positioning system) signals. The antenna transducer includes a primary antenna transducer portion for transducing signals generated to effectuate a communication service in the cellular communication system. And, the antenna transducer includes a second antenna transducer portion for transducing GPS signals transmitted to the mobile station. The primary and second antenna transducer portions are disposed upon a common substrate, and the second antenna transducer portion exhibits circular polarization characteristics.

    摘要： 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. The antenna according to the invention is flat, and therefore it can be fixed to the back wall of a mobile station, and the distance to the user's head is as large as possible.

    摘要： 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.
