Title
(EN) PHASED ARRAY ANTENNA AND ITS MANUFACTURING METHOD
(FR) ANTENNE EN RESEAU A ELEMENTS EN PHASE ET PROCEDE DE FABRICATION
Abstract
(EN)
A relatively small and inexpensive phased-array antenna provided even if the number of radiators is increased to enhance the gain. Spacings between the elements are small because of a multilayer structure including layers where a large number of radiators (15), phase-shifting units (16) each for shifting the phase of a high-frequency signal transmitted/received by the corresponding radiator, and a distributing/synthesizing unit (14) are provided respectively. The phase control layer (35) is constituted of as many internal wiring layers as the number of required drive lines (19), and a signal wiring to control each phase-shifting unit (16) is provided on the internal wiring layer. Therefore the areas for the wirings are small and the spacings between the elements are also small. The circuits repetitively provided in the phase-shifting units are constituted of chips integrally mounted on another board.

Cette antenne en réseau à éléments en phase, peu coûteuse, est de taille relativement réduite même si le nombre d'éléments rayonnants a été multiplié pour accroître le gain. Elle est constituée d'une structure multicouche dont les couches sont pourvues d'un grand nombre d'éléments rayonnants (15) et de compensateurs de phase (16) déphasant, chacun, la phase d'un signal à haute fréquence émis/reçu par l'élément rayonnant correspondant. Elle comporte également un répartiteur/synthétiseur (14). La couche de commande de phase (35) est constituée d'autant de couches de câblage interne qu'il existe de lignes d'attaque nécessaires (19) et un câblage de signal commandant chaque compensateur de phase (16) est monté sur la couche de câblage interne. De la sorte, la superficie occupée par les câblages est réduite de même que les intervalles existant entre les éléments. Les circuits montés de manière répétitive dans les compensateurs de phase sont constitués de microplaquettes faisant partie intégrante d'une autre carte.
