Abstract: A pager antenna system having two conductive containers which act as radiators and form a dipole antenna is disclosed. A metallic coil constructed of tubular material is positioned between the conductive containers and has a first end electrically connected to one of the containers. The tubular coil forms part of an antenna impedance matching network and also serves as a conduit for wires which interconnect circuit components located in each of the conductive containers. High frequency isolating chokes are connected in series with the interconnecting wires emerging from a second end of the tubular matching coil and prevent these wires from forming low impedance RF paths between the conductive containers. By making the RF impedance matching coil also serve as a conduit for low frequency interconnecting wires, fewer parts are required, the interconnecting wires are shielded from external influences, and low Q chokes can be used by connecting them across points which have a low RF impedance therebetween.
