Abstract
A single input multifrequency antenna is disclosed which comprises a plurty of radiating elements connected in series. The device may comprise multiple conformal edge slot radiators.
Claims7
A series-fed dielectric-filled antenna which allows operation at two or more independently selected frequencies, comprising at least two edge slot radiators comprising
- a dielectric substrate,
- a conductive plating on opposed exterior surfaces of said substrate, and
- at least one layer of conductive material within the substrate disposed in generally parallel relation to said exterior surfaces for separating the substrate into distinct edge slot radiators,
- each of said edge slot radiators comprising means for radiating at a different frequency, and
- a single coaxial line connecting said radiators in series, said coaxial line has one conductor thereof in conductive contact with one of said exterior plated surfaces, and the other conductor thereof in conductive contact with the other exterior plated surface.
2 more elements
A series-fed dielectric-filled antenna which allows operation at two or more independently selected frequencies comprising:
- at least two dielectric loaded edge slot radiators, each edge slot radiator comprising means for radiating at a different frequency and comprising a dielectric substrate having a conductive plating on opposed surfaces thereof,
- signal input means comprising a single coaxial line connecting said radiators in series and connected to each radiator at the center thereof,
- the inner conductor of said coaxial line is in electrical contact with the conductive plating on one side of the last radiator in said series, and the outer conductor of said coaxial line is in electrical contact with every other conductive plating on said at least two radiators.
