A double-sided PCB monopole Yagi-Uda antenna is disclosed, preferably as part of a directional beam antenna comprising a plurality of such antennas vertically mounted in spoke-like fashion around a metallic antenna PCB substrate. The monopoles are printed on a monopole dielectric substrate. Each antenna comprises a driver, a reflector and a pair of directors, each forming a strip etched at corresponding positions on either side of the PCB and electrically connected at a distal end of the strip by a via passing through the PCB. The driver is connected to the central conductor of a connector, while the reflector and directors are grounded. Because the monopoles are printed on a double-sided PCB, there is no bias in the azimuth pattern of antenna when vertically mounted as contemplated above. The use of a monopole dielectric substrate provides generally more consistent and improved performance over discrete wire monopole Yagi-Uda antennas.
Une antenne Yagi-Uda unipolaire à carte de circuits imprimés double face est décrite, de préférence comme faisant partie dune antenne directionnelle à faisceau comprenant une pluralité de telles antennes fixées verticalement à la manière de rayons dune roue autour dun substrat de carte de circuits imprimés dantenne métallique. Les monopoles sont imprimés sur un substrat diélectrique monopole. Chaque antenne comprend un élément excitateur, un réflecteur et une paire déléments directeurs, chacun formant une bande gravée à des emplacements correspondants de chaque côté de la carte de circuits imprimés et étant connecté électriquement à une extrémité distale de la bande par un trou dinterconnexion traversant la carte. Lantenne est reliée au conducteur central dun connecteur, alors que le réflecteur et les éléments directeurs sont mis à la terre. Comme les monopoles sont imprimés sur une carte de circuits imprimés double face, il ny a aucune polarisation dans le motif dazimut de lantenne lorsquelle est fixée verticalement comme prévu ci-dessus. Lutilisation dun substrat diélectrique unipolaire offre une performance généralement plus homogène et améliorée par rapport aux antennes Yagi-Uda unipolaires à fil distinct.
