The discone antenna is a small communication antenna with broad voltage standing wave ratio (VSWR) band-width. The discone antenna includes a conical antenna element and a disc antenna element adjacent the apex thereof and including a proximal electrically conductive planar member and a spaced apart distal electrically conductive planar member being electrical-ly connected together at respective peripheries thereof defining a folded ground plane. An antenna feed structure is coupled to the disc and conical antenna elements and includes a first conductor coupled to the proximal electrically conductive planar member, and a second conductor coupled to the conical antenna element and to the distal electrically conductive planar member. An impedance element, such as a resistor, may be connected between the second conductor and the distal electrically conductive pla-nar member.

L'invention concerne une antenne discône qui est une petite antenne de communication large bande à rapport étendu d'ondes stationnaires en tension (VSWR). Ladite antenne discône comprend un élément d'antenne conique et un élément d'antenne disque adjacent au sommet de l'élément conique, et est dotée d'un élément plan électroconducteur proximal et d'un élément plan électroconducteur distal séparé connectés électriquement ensemble à leurs périphéries respectives définissant un plan de sol replié. Une structure d'alimentation d'antenne est couplée à l'élément d'antenne conique et à l'élément d'antenne disque, et comprend un premier conducteur couplé à l'élément plan électroconducteur proximal, et un second conducteur couplé à l'élément d'antenne conique et à l'élément plan électroconducteur distal. Un élément d'impédance, tel qu'une résistance, peut être connecté entre le second conducteur et l'élément plan électroconducteur distal.
