Document Type and Number:
WIPO Patent Application WO/2007/108502
Kind Code:
A1
Abstract:
[PROBLEMS] To provide an antenna capable of assuring a sufficient radio reception
level and a radio receiver having the antenna. [MEANS FOR SOLVING PROBLEMS] An
antenna includes a columnar magnetic core formed by a ferromagnetic material,
a winding portion wound around the magnetic core, a flat-shape extension portion
extending from the end of the magnetic core, and an upright portion arranged at
least in one direction of the extension portion. Such an antenna is mounted on
a radio control clock of a wrist watch type which requires a small size and light
weight. Thus, it is possible to provide a radio control clock capable of assuring
a sufficient standard radio reception level while enabling a user to easily look
at the time display means.
