Abstract
A wristworn receiving device suitable for being worn about a wrist comprises a receiver (404) for receiving radio frequency signals on a particular operating frequency, a housing (142) for enclosing the receiver (404), a first wristband section (102) including a first wristband loop antenna portion (118) and a movable clasp member (122), and a second wristband section (104) including a second wristband loop antenna portion (134) terminated in a fixed clasp member (140). The first (118) and second (134) wristband loop antenna portions are partially resonated at the operating frequency. The second wristband loop antenna portion (134) is coupled to the first wristband loop antenna portion (118) and is positioned by the movable clasp member (122) at first (204) and second (202 or 206) positions along the first wristband loop antenna portion (118) so as to form a resonant loop antenna which remains substantially tuned to the operating frequency at the first (204) and second (202 or 206 ) positions.
