Abstract
The present invention relates to an improvement of an antenna apparatus for a transceiver that is capable of obtaining a stable operation of an antenna without being affected by different sizes of wrist bands or by a durability of a metal clasp. An antenna unit (14) is comprised of a strip shaped conductive plate (13), whose slot (13a) is formed in the longitudinal direction of wrist band (12), which is connected to a casing (11) of the wrist type transceiver (10). One conductive section of slot (13a) of the conductive plate (13) provides a feeding point (131) in order to supply a positive potential. The other conductive section (130b) provides a second feeding point (132) in order to fix the other conductive section (130b) to the ground potential. A capacitance element (19) is attached between one conductive section (130a) and the other conductive section (130b) of the conductive plate (13).
