Abstract

A laminated antenna structure includes a substrate, a first conductive circuit layer, an insulating colloidal layer, a second conductive circuit layer and a conductive structure. The first conductive circuit layer is disposed on or above the substrate, the second conductive circuit layer is disposed above the first conductive circuit layer, and the insulating colloidal layer is disposed between the first and the second conductive circuit layers. The first conductive circuit layer, the insulating colloidal layer and the second conductive circuit layer form a laminated capacitive structure. The conductive structure is electrically connected to a signal source on the substrate, and the signal source is electrically connected to at least one of the first conductive circuit layer and the second conductive circuit layer. The insulating colloidal layer contains catalyzers.
