Abstract

Antenne à structure de guide d'ondes, comprenant une base constituée d'un métal plat et mince; une plaque de rayonnement constituée d'un métal plat et mince disposée parallèlement à la base à une certaine distance de celle-ci; et une série de parois latérales en métal plat et mince, fixée à cette base et à cette plaque de rayonnement et disposées dans l'espace compris entre cette base et cette plaque de rayonnement de manière à constituer une série de guides d'ondes reliés les uns aux autres. La plaque de rayonnement et les parois latérales sont réunies par soudage par points à intervalles spécifiques. La base et les parois latérales se présentent de préférence sous forme d'un bloc unique en métal.
