Title (EN) ANTENNA DIELECTRIC CAP LOADING
(FR) CHARGEMENT DE CAPUCHONS DIÉLECTRIQUES D'ANTENNES
Abstract: front page image
(EN)Antenna miniaturization is a big engineering challenge because of the fundamental limitations that restrict antenna performance. In the present invention a new dielectric cap loading technique for improving small antenna element performance exploiting the space capacitance is introduced. The cap loading technique can be easily realized e.g. by 3D dielectric blocks, such as ceramic blocks.
(FR)L'invention concerne la miniaturisation des antennes, qui constitue un important défi technique en raison des limitations fondamentales qui restreignent les performances des antennes. La présente invention introduit une nouvelle technique de chargement de capuchons diélectriques destinée à améliorer les performances de petits éléments d'antennes exploitant la capacitance d'écartement. La technique de chargement de capuchons peut être facilement réalisée, par ex. au moyen de blocs diélectriques 3D tels que des blocs en céramique.
