Claim:
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; said pair of horns having substantially identical shapes, extending in opposite directions to distal tips having the appearance of a whale's tail when viewed from a position normal to said first substrate surface; 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 from a widest point substantially in-between said distal tips, 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.
