Title:
MULTI-FREQUENCY SLOT ANTENNA, TERMINAL DEVICE AND ANTENNA RESONANCE FREQUENCY ADJUSTMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2021/249170
Kind Code:
A1
Abstract:
The present disclosure relates to the technical field of 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 the terminal device, and the terminal device comprises a metal housing. According to an embodiment, the antenna comprises: a slot provided on the metal housing, the slot having a first end and a second end opposite to each other in the length direction; a feed terminal provided across the slot and located between the first end and the second end; and a first capacitor provided in the slot, two electrodes of the first capacitor being respectively connected to two sides of the slot in the width direction. Furthermore, in the length direction, the first capacitor is located at a position where no voltage value under an original value, provided when the first capacitor is not provided in the slot, of the multiple-order resonance frequency of the antenna is zero, such that the working frequency of the antenna includes the multiple-order resonance frequency.
