1. A radiator element comprising:
- a substrate;
a first substrate surface, a portion of which is covered with a conductive material, and a portion of which is uncovered;
said conductive material forming a pair of horns having substantially identical shapes, said horns each extending in opposite directions to distal tips;
a first cavity formed by said uncovered portion in-between said pair of horns;
said first cavity having a mouth portion, said mouth portion beginning at a first edge along a line extending between said distal tips;
said mouth portion reducing in cross-section as it extends from said first edge in-between said two horns to a narrowest point in between said pair of horns;
said first cavity extending away from said narrowest point in a curved direction into a first one of said horns; and
a feedline electrically communicating at a first end with a second one of said horns and adapted at a second end for electrical communication with an RF receiver or transceiver.

Abstract
A radiator element for RF transmission and reception over a wide band of frequencies. The radiator element is formed of conductive material on substrate surface of conductive material in the form of a pair of horns extending in opposite directions to distal tips defining the widest distance of a mouth of a cavity. The mouth reduces in cross-section to a narrowest point in between said pair of horns. The resulting radiator element will radiate and receive frequencies between frequencies the distance of the widest point and narrowest point are sized to receive.
