Abstract
A broadband-operable impedance filter has capacitive elements of variable capacitance in the signal path, an inductive element in a parallel path connected in parallel to the signal path, and inductive elements in the ground path. The impedance filter allows communication in a first frequency band and the reception of HF signals in a second frequency band.
