Abstract:
1. A broadband mobile antenna assembly comprising: a whip; a base defining a housing; an adaptor extending on top of the base above the housing, for receiving a lower end of the whip; a mounting element extending in the housing, the mounting element having two opposite PCB mounting side surfaces and two opposite coil mounting surfaces; two PCBs, each PCB being mountable on the corresponding PCB mounting side surface and fitting in the housing; and matching circuitry integrated on the two PCBs, the matching circuitry having a conductor for connection to the whip when the whip is inserted in the adaptor, and a conductor for external cable connection, the matching circuitry having a series resonant network operatively connected to a parallel resonant network for increasing a bandwidth of the antenna assembly, the series and parallel resonant networks each having a coil mountable to the corresponding coil mounting surface.
