摘要： A receiver device has a plurality of signal reception processing circuits, which processes GPS positioning signals of different carrier wave frequencies received by an antenna. In the receiver device, the positioning signals are converted into intermediate frequency signals in a first stage, which includes phase shifters, mixers and complex filters. The receiver device further has dividers of frequency-dividing ratios, which are set variably in accordance with the carrier wave frequencies in the respective signal reception processing circuits. By changing the frequency-dividing ratios, the receiver device can be adapted to receive other positioning signals.

摘要： A multi-band antenna includes two conductive wirings and unit circuits cascaded along the conductive wirings. Each unit circuit includes a communication unit, a first capacitor and a second inductor. The communication unit connects between the conductive wirings through a first inductor and a second capacitor connected in series with the first inductor. The first capacitor and the second inductor are inserted in at least one of the conductive wirings. The second inductor is connected in parallel with the first capacitor. Alternatively, the unit circuit includes a communication unit connecting between the conductive wirings through a first inductor, and a first capacitor inserted in at least one of the conductive wirings. The first inductor, the first capacitor, a third capacitor disposed between the conductive wirings, and a third inductor disposed on at least one of the conductive wirings satisfy a relationship expressed by the expression 2.

摘要： A navigation system incorporating an antenna includes a cabinet constructed of electroplated case and cover. An antenna element is integrated to the cabinet and electrically connected with the cover that is a ground of the antenna element. With this configuration, the cabinet and the antenna element can be installed in a vehicle at once and wiring of the antenna element outside the cabinet can be eliminated. Thus, installability of the navigation system is improved in comparison with known devices. Furthermore, the cover is formed such that its surface is larger than that of the antenna element. As a result, directivity of the antenna element is properly secured.
