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.
