ABSTRACT:
A wrist-type wireless instrument equipped with an antenna body that is formed on a wrist band is disclosed. The wireless instrument provides a simple compact arrangement within the wireless instrument casing and provides a large antenna gain. The wireless instrument is equipped with first and second wrist band members 21a and 21b respectively connected to each side of a wireless instrument casing 20 containing a wireless instrument circuit. A conductive plate 24 is fixed to the first and second wrist band members 21a and 21b. A slot 25 is formed in the conductive plate 24 so as to extend in the length dimension of the band. A capacitive element 26 is loaded across two divided sections of the conductive plate 24 that are defined by the slot 25, at a position substantially in the middle portion with respect to the length dimension of the conductive plate 24.
