Abstract
A cone antenna has at least one resistor electrically coupled to the radiating structure of the cone antenna. The capacitor may be part of a resistor network that is electrically connected to the cone. One or more patches may be coupled to the resistor network which act as a capacitor. A feed card may be embedded within a ground plane to enable the exterior of an antenna assembly to be conformal with an outer surface of a platform carrying the cone antenna.

A cone antenna assembly comprising:
- a cone including a frustoconical sidewall extending from a first end to a second end, the first end having a diameter greater than the second end;
- a first pin in electrical communication with the frustoconical sidewall;
- at least one resistor in electrical communication with the first pin;
- a feed card in electrical communication with the cone adjacent to the second end;
- a ground plane including a first surface opposite a second surface;
- and
- a recess formed in the second surface shaped complementary to the feed card, and the feed card is disposed within the recess,
- wherein the cone extends outward from the first surface on the ground plane.
A cone antenna assembly comprising:
