An improved slot array antenna with a circular aperture and linear polarization is shown to be made up of a plurality of slotted waveguides having different lengths and different widths. The slots in the waveguides are positioned to optimize amplitude taper in any plane passing through the center of the array normal to the surface thereof and to maximize the number of such slots.

An antenna, adapted to be used as a monopulse antenna in a guided missile, is shown to comprise four separate microstrip circuits in different quadrants of a circular microstrip arrangement, each one of such microstrip circuits being made up of an array of contiguous rectangular meshes with the widths of the shorter sides of such meshes being varied to provide an amplitude taper.
