Abstract
(EN)
Disclosed in the present application are loop antennas for wireless charging, comprising an extra-body planar loop antenna, and an intra-body planar loop antenna. The intra-body planar loop antenna is used for being placed inside the body, and the extra-body planar loop antenna is used for being placed outside the body on the skin. The extra-body planar loop antenna comprises an extra-body antenna substrate, extra-body loop radiation patches, paired connecting radiation patches, and a patch capacitor. At least one extra-body radiation patch gap is provided in the loop radiation patches. The patch capacitor is arranged at the extra-body radiation patch gap. The extra-body loop radiation patches and the paired connecting radiation patches form a circuit. The extra-body loop radiation patches, the paired connecting radiation patches, and the patch capacitor are all on a same surface of the extra-body antenna substrate. In the present invention, wireless transmission antennas having a planar and multi-loop design are used to reduce antenna surface area, and a patch capacitor is used to improve energy transmission efficiency.

La présente invention concerne des antennes à cadre pour une charge sans fil, comprenant une antenne à cadre plane extra-corporelle, et une antenne à cadre plane intra-corporelle. L'antenne à cadre plane intra-corporelle est utilisée pour être placée à l'intérieur du corps, et l'antenne à cadre plane extra-corporelle est utilisée pour être placée à l'extérieur du corps sur la peau. L'antenne à cadre plane extra-corporelle comprend un substrat d'antenne extra-corporelle, des plaques de rayonnement à cadre extra-corporelles, des plaques de rayonnement de connexion appariées, et un condensateur à plaques. Au moins un espace de plaque de rayonnement extra-corporelle est prévu dans les plaques de rayonnement à cadre. Le condensateur à plaques est disposé au niveau de l'espace de plaque de rayonnement extra-corporelle. Les plaques de rayonnement à cadre extra-corporelles et les plaques de rayonnement de connexion appariées forment un circuit. Les plaques de rayonnement à cadre extra-corporelles, les plaques de rayonnement de connexion appariées et le condensateur à plaques se trouvent tous sur une même surface du substrat d'antenne extra-corporelle. Dans la présente invention, des antennes de transmission sans fil ayant une conception planaire et à plusieurs cadres sont utilisées pour réduire la surface d'antenne, et un condensateur à plaques est utilisé pour améliorer l'efficacité de transmission d'énergie.
