Abstract
A low profile non-resonant traveling wave slot antenna operating over broad frequency bands is in the form of a multiple layer circuit, which includes a generally planar slotted conductor sheet having an open smoothly curved tapered planar slot therein and a three-dimensionally smoothly curved stripline conductor sheet having an elongated stem portion electrically connected at its distal end to a feed point on top of the slotted conductor sheet and extending downwardly through the slot therein and terminating in an enlarged smoothly tapered portion to transition the characteristic impedance between the feed point and an aperture impedance matched to free space.
