Title
(EN) ANTENNA CIRCUIT FOR MINIATURE RADIO RECEIVER
(FR) CIRCUIT D'ANTENNE POUR RECEPTEUR RADIO MINIATURISE
Abstract
(EN) The mobile miniature radio receiver has, as antenna, an elongated dipole. The antenna wires extend along the edge of one or a plurality of printed circuit boards of the receiver and are connected at their ends to conducting surfaces. The conductor tracks of the board or boards, which extend in parallel to the antenna form an ohmic-capacitive shunt and are therefore, for the RF signals, uncoupled at the surroundings of the antenna base.
(FR) Le récepteur radio miniaturisé, mobile, présente comme antenne un dipôle allongé. Les fils d'antenne s'étendent le long du bord d'une ou plusieurs plaquettes de circuits imprimés du récepteur et sont reliés, à leur extrémité, à des surfaces conductrices. Les pistes conductrices de la ou des plaquettes, qui s'étendent parallèlement à l'antenne forment une dérivation ohmique-capacitive et sont donc, pour les signaux HF, découplées aux alentours de la base de l'antenne.
