Abstract (en)
[origin: US4947179A] A magnetic antenna for a radio receiver such as a radio timepiece can be installed under restricted spacial conditions in a small housing or used as an antenna for a radio wristwatch. The antenna includes a core extending through a coil. The core is made of flexible, high permeability material, so that a flexible connection with the watch is obtained. A multiple flat strip conductor integrated into a watch bracelet serves as the connection between the coil and the receiver. Instead of being flexible, the core may be rigid but pre-formed in a non-linear shape.
