WIPO Patent Application WO/2016/187886

Kind Code:

A1

Abstract:

Provided are a slot antenna and an electronic device, which relate to the field of antennas. The slot antenna comprises a printed circuit board with a slot, a first capacitor, a radio frequency signal source, a transmission line and a ground line; the printed circuit board is grounded; one end of the slot is open, and the other end is closed; the first capacitor and the ground line are arranged on the printed circuit board; the first capacitor is located at an open end of the slot and is arranged at one side of the slot; the first capacitor and the radio frequency signal source are connected via the transmission line, and the radio frequency signal source is connected to the transmission line and the ground line; and the radio frequency signal source is used for activating a feed-in signal and feeding the feed-in signal in the open end of the slot via the first capacitor. By means of the present invention, a signal is fed in an open end of a slot via a capacitor, impedance matching can be achieved only by selecting a capacitor with a fixed capacitance value, the requirement of a fabrication process is relatively low, and meanwhile, the volume of the capacitor is relatively small, and the space usage of a slot antenna can be reduced.
