A planar edge-slotted and end-fed traveling wave antenna is designed for monopulse operation, with an odd array of parallel elements interleaved with an even array of parallel elements. The even elements have an amplitude taper that is an arithmetic sum of Taylor and Bayliss amplitude tapers, while the odd elements have an amplitude taper that is an arithmetic difference of the Taylor and Bayliss tapers. Transmit energy is fed to both the odd and even elements, and the resulting radiation produces a pencil beam of a predetermined beamwidth for illumination of a distant target. The return excitation for the odd and even elements is combined to produce sum and difference monopulse patterns.
