Abstract
An active antenna module is disclosed. The active antenna module comprises a loop antenna, a RF transistor, a LR series circuit, a first bypass capacitor and a second bypass capacitor. The RF transistor comprises a control port, a first port, and a second port. Each of two ends of the loop antenna is electrically connected to one of the control port and the second port, and the control port and the second port are out of phase. The second port is electrically connected to the first port via the first bypass capacitor. The first port is electrically connected to ground via the LR series circuit. The second bypass capacitor and a resistor of the LR series circuit are connected in parallel.
