摘要： Embodiments of the present invention provide a multi-band antenna and a terminal device. The multi-band antenna includes: a feeding part is connected to a capacitor component to form a feeding circuit, and a feeding matching circuit is electrically connected between a feeding radio frequency circuit and the feeding circuit; a radiation part is electrically connected both to the feeding circuit and a grounding part; the grounding part is electrically connected to a ground plane; a first resonant circuit is formed from the feeding circuit to an end that is of the radiation part and that is away from the grounding part; and the first resonant circuit generates a first resonance frequency and a second resonance frequency.

摘要： Embodiments of the present invention provide a slot antenna and an electronic device, and relate to the antenna field. The slot antenna includes: a printed circuit board having a slot, a first capacitor, a radio frequency signal source, a transmission line, and a ground cable. 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 cable are disposed on the printed circuit board, the first capacitor is located on the open end of the slot, and is disposed on one side of the slot; the first capacitor is connected to the radio frequency signal source by using the transmission line, and the radio frequency signal source connects the transmission line to the ground cable; and the radio frequency signal source is configured to: stimulate a feeding signal, and feed the feeding signal to the open end of the slot by using the first capacitor. In the present invention, a signal is fed to the open end of the slot by using a capacitor, and impedance matching can be implemented as long as a capacitor having a fixed capacitance is selected, so that a requirement on a manufacturing process is relatively low. In addition, a volume of the capacitor is relatively small, so that space occupied by the slot antenna can be reduced.
