Abstract
A wrist-worn electronic device configured to transmit and receive wireless signals in two frequency bands comprises a bezel loop antenna, first and second signal processing elements, a diplexer, and a tuning element. The bezel loop antenna has a first impedance and is configured to wirelessly receive first and second electronic signals simultaneously. The first and second signal processing elements process the first electronic signal having a frequency in a first frequency band and the second electronic signal having a frequency in a second frequency band. The diplexer is configured to receive the first and second electronic signals and output the first electronic signal to the first signal processing element and the second electronic signal to the second signal processing element. The tuning element has a second impedance causing the bezel loop antenna to wirelessly receive electronic signals in the first frequency band and electronic signals in the second frequency band.
