Biometric monitoring devices, including various technologies that may be implemented in such devices, are discussed herein. Additionally, techniques, systems, and apparatuses are discussed herein for providing a hybrid antenna including an RF radiator and an electrically coupled inductive loop. The hybrid antenna is capable of providing both RF and induction functionality, e.g., radio frequency transmission/reception capabilities for Bluetooth as well as near-field-communications (NFC) functionality via the inductive loop. The inductive loop may be in conductive contact with the RF radiator or may be inductively coupled with the RF radiator and not in conductive contact with the RF radiator. The inductive loop may act as a planar element of a planar inverted-F antenna (PIFA).

Hybrid radio frequency / inductive loop antenna

A hybrid antenna including a piezoelectric device and an RF radiator. The hybrid antenna is capable of providing both RF and piezoelectric device functionality, e.g., radio frequency transmission/reception capabilities for radio frequency devices as well as sound-producing and/or energy-scavenging functionality via the piezoelectric device. The piezoelectric device may be in conductive contact with the RF radiator or may not be in conductive contact with the RF radiator.
