Abstract
(EN)
The present disclosure provides an antenna structure and a mobile terminal. The antenna structure comprises: an antenna radiator; a ground plate, a clearance region being formed between the ground plate and the antenna radiator; a signal source, a first end of the signal source being connected to the ground plate; a first capacitor, a first end of the first capacitor being connected to a second end of the signal source, a second end of the first capacitor being connected to the antenna radiator; and a first impedance matching network separately connected to the antenna radiator and to ground. The antenna structure generates at least two of a first resonant mode, a second resonant mode, and a third resonant mode. Resonance in the first resonant mode occurs at a quarter wavelength of a first frequency band, and resonance in the second resonant mode occurs at a quarter wavelength or a three-quarter wavelength of a second frequency band.

La présente invention concerne une structure d'antenne et un terminal mobile. La structure d'antenne comprend : un élément rayonnant d'antenne ; une plaque de masse, une région de dégagement étant formée entre la plaque de masse et l'élément rayonnant d'antenne ; une source de signal, une première extrémité de la source de signal étant connectée à la plaque de masse ; un premier condensateur, une première extrémité du premier condensateur étant connectée à une seconde extrémité de la source de signal, une seconde extrémité du premier condensateur étant connectée à l'élément rayonnant d'antenne ; et un premier réseau d'adaptation d'impédance connecté séparément à l'élément rayonnant d'antenne et à la masse. La structure d'antenne génère au moins deux parmi un premier mode résonant, un deuxième mode résonant et un troisième mode résonant. La résonance dans le premier mode résonant se produit à une longueur d'onde de quart d'onde d'une première bande de fréquence, et la résonance dans le deuxieme mode de résonance se produit à une longueur d'onde de quart d'onde ou à une longueur d'onde de trois quarts d'une seconde bande de fréquence.
