MATCHING ELEMENT FOR MOBILE ANTENNA

摘要

A matching element for a mobile antenna includes a coupling box having a coaxial connector, a circuit board provided within the coupling box and a central conductor provided within a coaxial screen for shielding the central conductor. The central conductor extends between the circuit board and the coaxial connector. The coaxial screen is electrically connected at one end to an outer shield of the coaxial connector and thence to the coupling box, and the other end terminates adjacent the circuit board. The central conductor with the coaxial screen are led along an indirect route within the coupling box, the route being configured in relation to conductive patterns of the circuit board so as to minimise interaction between electrical fields that, in use, are radiated within the coupling box, thus minimising signal losses.
