Abstract
An antenna component includes a primary coil that has a first end and a second end and a first secondary coil that has a third end electrically connected to the first end via a capacitor and a fourth end electrically connected to the second end. The antenna component includes a first terminal electrically connected to the first end and a second terminal electrically connected to the second end. The capacitor forms a resonator with the primary coil and the first secondary coil. The first terminal and the second terminal are configured to receive a signal to the antenna component, the capacitor forms a resonator circuit with the primary coil and the first secondary coil, and the resonator circuit is configured to cause a resonance when the signal has a resonance frequency of the resonator circuit.
