Abstract
Antenna system embodiments are shown which are especially suited for mounting on aircraft and for operation across widely-spaced frequency bands. Embodiments include blade members positioned in a ring arrangement and tuning circuits that are each coupled between a respective pair of the blade members and configured to successively remove blade members from operation as the operational frequency increases.
Claims20
An antenna system, comprising:
- a plurality of blade members positioned in a ring arrangement;
- and
- a connective path coupled to exchange electromagnetic energy with a base member of said blade members.
An antenna system, comprising:
- a plurality of blade members positioned in a ring arrangement;
- and
- a plurality of reactive elements that are each coupled between a respective pair of said blade members;
- wherein one of said blade members is a base member and said reactive elements are configured to provide reactances that generally increase with distance from said base member.
