Abstract
Described are electronic devices, and specifically provides a multi-frequency slot antenna, a terminal device and an antenna resonance frequency adjustment method. The antenna is applied to a terminal device, and the terminal device includes a metal casing. According to an example, the antenna includes a slot provided in the metal casing, the slot having a first end and a second end opposite to each other in a length direction; a feed terminal across inside of the slot and located between the first end and the second end; and a capacitor provided in the slot, two electrodes of the capacitor being respectively connected with two sides of the slot in a width direction. Furthermore, in the length direction, the capacitor is located at a position where voltages are not zero at original values of multiple orders of resonance frequencies of the antenna when the capacitor is not provided in the slot. In this way, an operating frequency of the antenna includes multiple orders of resonance frequencies.
