A crossed slot fed microstrip antenna (100). The antenna (100) includes a conducting ground plane (125), which has at least one crossed slot (125), and at least two feed lines (105). The feed lines (105) have respective stub regions (115) that extend beyond the crossed slot (125) and transfer signal energy to or from the crossed slot (125). The antenna (100) also includes a first substrate (150) disposed between the ground plane (120) and the feed lines (105). The first substrate (150) includes a first region and at least a second region, the regions having different substrate properties. The first region is proximate to at least one of the feed lines (105).

L'invention concerne une antenne microruban alimentée à fente croisée (100), qui comprend un plan de sol conducteur (125), présentant au moins une fente croisée (125), et au moins deux lignes d'alimentation (105), lesquelles présentent des tronçons respectifs (115) qui s'étendent au-delà de la fente croisée (125) et transfèrent l'énergie du signal vers la fente ou depuis la fente (125). L'antenne (100) comporte en outre un premier substrat (150) entre le plan de sol (120) et les lignes d'alimentation (105). Le premier substrat (150) comporte une première région et au moins une seconde région, chacune avec des propriétés de substrat différentes. La première région est proche d'au moins une des lignes d'alimentation (105).
