Antenna
First Claim
1. A sectoral antenna for use with finline electromagnetic wave transmission means of the type having two thin coplanar fin elements disposed with adjacent edges forming a narrow channel transmission path having a flare from a first end at a predetermined angle, said antenna comprising first and second triangular shaped planar members, each having a vertex and a base opposite said vertex, said triangular shaped planar members disposed in planes normal to said plane of said fin elements, and supported respectively by said adjacent edges of said fin elements along said flare such that said vertex of each triangular shaped planar member is positioned adjacent said first end of said narrow channel and housing means enclosing said transmission path.

Abstract
A broad band millimeter wave finline antenna includes a finline transmission means having a flared end portion formed by tapering the adjacent edges of the finline elements and affixing planar sectoral conducting members to the tapered edges. The finline transmission means may be mounted in a housing that provides a transition for coupling the antenna to exterior waveguides or other transmission means.
