An antenna oscillator unit includes a radiator and a balun support. The radiator is fixed to the balun support and includes a plurality of low-frequency oscillator arms circumferentially distributed along the balun support. Each of the low-frequency oscillator arms includes two radiating sections connected to each other and a connecting section connecting the two radiating sections to form a closed loop. The two radiating sections are substantially perpendicular to each other. The antenna oscillator unit of some embodiments can avoid mutual coupling of signals from the antenna oscillator unit and an adjacent high-frequency oscillator and can improve the capability to radiate electromagnetic signals.

Disclosed is an antenna device for measuring biometric information by using dark mode excitation. The antenna device according to an embodiment may include a conducting wire forming a loop. A current may be induced into the loop through an interaction with a magnetic field generated by an antenna connected to a power source. Information on an analyte may be sensed using a magnetic field formed based on the current induced into the loop.
