A receiver apparatus includes: a main unit device; and a junction cable transmitting one or both of signal and electric power between the main unit device and an external device. The junction cable is a multicore coaxial cable having a plurality of core wire cables and a covered wire covering the plurality of core wire cables, and only the covered wire is cut locally so that the covered wire is divided into a main unit device-side covered wire and an external device-side covered wire. The main unit device transmits one or both of the signal and electric power by the core wire cable, and the main unit device-side covered wire or the core wire cable is connected to an antenna input port of a built-in tuner, and the main unit device receives a desired broadcast wave with the tuner using a high-frequency signal induced in the main unit device-side covered wire or the external device-side covered wire.

A PDA includes a printed-circuit board on which at least one printed antenna pair having two chip-like printed antennas, which receive linearly polarized signals and are disposed along axes orthogonal to each other, is mounted. In each of the printed antennas, an open end is formed of at least two antenna conductors separated from each other. Besides, in the printed-circuit board, a ground required by one or plural other modules is disposed so as to surround a surrounding area of at least three sides of four sides forming a rectangular section in each of the printed antennas, and each of the printed antennas is disposed and mounted so that a remaining one side faces an edge portion of the printed-circuit board. While the PDA can receive circularly polarized signals very effectively, the degree of freedom in layout is greatly expanded and miniaturization can be realized.
