Abstract

An antenna apparatus and an electronic apparatus are provided. The electronic apparatus includes the antenna apparatus. The antenna apparatus includes a radiator, a first and a second impedance control circuit. The radiator receives and transmits a radio frequency (RF) signal. The first impedance control circuit is electrically connected to the radiator and transmits the RF signal. The second impedance control circuit includes an impedance matching circuit and an inductor. The first end of the impedance matching circuit is electrically connected to the radiator. The impedance matching circuit adjusts the impedance matching of the radiator and transmits a sensing signal. The inductor is electrically connected to the second end of the impedance matching circuit. The inductor transmits a sensing signal, and blocks the RF signal. Accordingly, the structures of the antenna and the circuit can be simplified, and the influence between the RF signal and the sensing signal can be reduced.
