Wideband Structural Antenna Operating in the Hf Range, Particularly For Naval Installations
First Claim
1. Antenna system for operation in the HF frequency range, particularly for naval communications, comprising a linear radiating arrangement (14) adapted to be operatively associated with a ground conductor (GND) and at least one electrical impedance device (Z1-Z4),characterized in that the said linear radiating arrangement (14) is coupled to a pre-existing naval structure (F) which has a predominantly vertical extension and is electrically conducting.

Abstract
A structural antenna system for operation in the HF frequency range, particularly for naval communications, is described, comprising at least one linear radiating arrangement (14) adapted to be operatively associated with a ground conductor (GND) and at least one electrical impedance device (Z1-Z4), in which the aforesaid linear radiating arrangement (14) is coupled to a pre-existing naval structure which has a predominantly vertical extension and is electrically conducting, such as a funnel (F). A structural antenna system with multiple feed comprises a plurality of linear radiating arrangements (114) positioned in meridian planes of the naval structure of the funnel type (F), spaced at equal angular intervals.
