Claim Text:
1. Three-dimensional integrated structure, comprising: a support element, an interface device connected to the support element by first electrically conductive connection means, an integrated circuit arranged between the support element and the interface device and connected to the interface device by second electrically conductive connection means, the integrated circuit comprising a semiconductor substrate having a first face supporting an interconnection part having a plurality of metallization levels enclosed in an insulating region, a filler region standing between the second electrically conductive connection means and between the interface device and the integrated circuit, and means forming an antenna, having a first antenna substrate and a second antenna substrate which are separated by an earth plane equipped with an aperture, a radiating element separated from the earth plane by the first antenna substrate, an excitation element separated from the earth plane by the second antenna substrate, the excitation element being produced within an upper one of the metallization levels of the interconnection part, and a reflector produced within a lower one of the metallization levels of the interconnection part facing the excitation element, the aperture being configured in such a way as to permit electromagnetic coupling between the excitation element and the radiating element, the interface device incorporating the radiating element, the first antenna substrate and the earth plane, the integrated circuit incorporating the excitation element, and the second antenna substrate being formed by at least a part of the filler region.
