Patent ID: 7456800

Claim:
A receiver antenna system of broad bandwidth comprising: a plurality of active, vertical individual antennae each with an electrically-active antenna height adapted to a respective received frequency range, wherein: the mutual electromagnetic coupling between the individual antennae, which are positioned at a small spacing distance, is minimized, by optimization of individual mechanical and electrically-active antenna heights, individual antenna diameters, spacing distances between individual antennae, and the input impedances of active base-point electronics disposed at respective base points associated with the individual active antennae, wherein in each of the individual antennae, the electrically-active antenna height is optimized by an arrangement of conductor portions disposed along a vertical length of the antenna wherein one of a plurality of impedance elements is disposed between each consecutive pair of conductor portions, the optimized arrangement of the impedance elements relative to one another takes place both within one of the individual antennae and also between the individual antennae, and the length of each subsequent conductor portion of each individual antenna decreases with increasing distance of the conductor portion from a base point located at an open end of the antenna.
