Paper Title
High Performance Antenna Design For Wearable Smart Watch
Abstract
In this paper, a high performance antenna design for wearable smartwatch using controlled endless metal rim
mode is introduced. The proposed antenna occupies a clearance of 1 mm × 4 mm on a 30 mm × 20 mm ground plane. The
metal rim with a dimension of 34 mm × 24 mm surrounds the ground plane without any connection, so the metal rim is
separated from the ground plane with a gap of 2 mm. In addition, a lumped capacitor between the metal rim and the ground
plane is inserted to control the characteristic mode of the metal rim. The performance of the proposed antenna is compared
with a reference antenna without the inserted capacitor between the metal rim and ground plane through simulation and
measurement, and a wide bandwidth is generated by the proposed technique.
