A phased array antenna (6) includes a substrate (11), and multiple radiating elements (8) confbrmally mounted as micro-strip on the substrate. Each of the radiating elements is of a triangular shape, and four of the radiating elements are arranged to form a crossed bowtie cloverleaf radiator. In addition, the four radiating elements form two pairs of radiating elements, and the two pairs of radiating elements are orthogonal to each other. The radiating elements are disposed on a front surface of the substrate, and a RF center conductor (21, 22, 23, 24) is orthogonally oriented toward a rear surface of the substrate and connected to one of the radiating elements for feeding a RF signal to the one radiating element.

L'invention concerne une antenne réseau à commande de phase comprenant un substrat, de multiples éléments de rayonnement montés de façon conforme comme des microbandes sur le substrat. Chacun des éléments de rayonnement possède une forme triangulaire, et quatre de ces éléments sont disposés de manière à former un radiateur en trèfle à boucle en croix. En outre, les quatre éléments de rayonnement forment deux paires d'éléments de rayonnement, ces paires sont orthogonales l'une par rapport à l'autre. Les éléments de rayonnement sont placés sur une surface avant du substrat, et un conducteur central RF est orienté de façon orthogonale par rapport à une surface arrière du substrat et relié à un des éléments de rayonnement afin de transférer un signal RF vers un élément de rayonnement.
