Definitions

  • Each radiating patch also includes a ring area cut- out from the patch, exposing a portion of the dielectric material underneath the radiating patch.
  • the ring may have a rectangular shape, as disclosed in the co-pending patent application.

  • Fig. 4 is a simplified top view of one specific embodiment of a ring microstrip antenna array according to the present invention;
  • Fig. 5 is a simplified top view of another specific embodiment of a ring microstrip antenna array according to the present invention;
  • each resonant patch 130 is 41.5 mm long, more than 40% smaller than typical quarter wavelength radiators. It is believed that the increased coupling provided by these double ring patches allows each of the patches 130-133 to be positioned much closer together than in prior arrays.

Abstract

Dispositif d'antenne microruban annulaire (100) de dimensions réduites présentant néanmoins des caractéristiques remarquables de rayonnement directionnel et une altération minime du fonctionnement en cas d'utilisation à proximité étroite d'autres appareils électroniques ou du corps humain. Ce dispositif d'antenne microruban (100) comprend un élément à polarisation horizontale (120) et une série de pastilles rayonnantes (130, 133) réalisées chacune dans un matériau conducteur, ainsi qu'une couche diélectrique (110) positionnée entre l'élément à polarisation horizontale (120) et les pastilles rayonnantes (130, 133), de manière à constituer ensemble un dispositif rectangulaire. Chacune des pastilles rayonnantes (130, 133) comporte deux bords latéraux (162, 164), un bord principal rayonnant (160) et un bord inférieur (166). Toutes les pastilles sont orientées dans la même direction. Un court-circuit (142, 144) établi le long du bord inférieur (166) de chacune des pastilles, génère une image 'miroir' de chacune de ces pastilles par rapport à son bord inférieur. Le bord inférieur peut être entièrement écourté ou n'être écourté que sur une ou plusieurs de ses parties.
