Abstract
The present invention is to provide a resonance circuit, which is applicable to a circuit board of a first electronic device provided thereon with a circuit layout, a high-speed connector (e.g., a USB 3.0 connector) at a lateral side of the circuit layout for connecting with a second electronic device, and an antenna for enabling the circuit board to receive and transmit wireless information at a predetermined frequency. The connector and antenna are respectively connected to first and second connecting points of the circuit layout, and the distance between the two connecting points is not less than one wavelength. The resonance circuit is connected to a third connecting point of the circuit layout provided between the above two connecting points, such that the resonance frequency of the resonance circuit covers the reception and transmission frequencies of the antenna, for effectively inhibiting interference between the connector and the antenna.
