Abstract

L'invention concerne un agencement d'antenne (6), destiné à une extrémité avant de radar (60), comportant des antennes à haute fréquence (4) destinées à convertir de l'énergie électromagnétique et un réseau d'alimentation (1) au moyen duquel les antennes à haute fréquence (4) peuvent être raccordées à une unité d'émission et/ou une unité de réception (61). Les antennes à haute fréquence (4) et le réseau d'alimentation (1) sont formés par des pistes conductrices d'une carte à circuit imprimé (68), et le réseau d'alimentation (1) comporte une première ligne d'alimentation (2) dans une première direction spatiale (z) et au moins deux deuxièmes lignes d'alimentation (3) dans une deuxième direction spatiale (y). Une deuxième ligne d'alimentation (3) est raccordée aux bornes (22) de la première ligne d'alimentation (2) et une antenne à haute fréquence (4) est raccordée aux bornes (32) des deuxièmes lignes d'alimentation (3). Pour rendre une caractéristique de rayonnement de l'extrémité avant de radar (60) particulièrement facile à adapter à une application particulière, selon l'invention la première ligne d'alimentation (2) et les deuxièmes lignes d'alimentation (3) forment une boucle (20, 30) entre deux bornes adjacentes (22, 32) et une longueur (50, 52) de la ligne d'alimentation concernée (2, 3) entre les deux bornes adjacentes (22, 32) peut être spécifié à une position constante des antennes à haute fréquence (4) par une forme respective de la boucle (20, 30).
