MILLIMETRE WAVE MONOPULSE PRINTED ANTENNA ARRAY

摘要

This paper presents the design and construction of a millimetre wave antenna to be used in a monopulse radar system. The antenna must presents a narrow pencil beam with a monopulse double beam in both principal planes. Design conditions are restricted to low cost fabrication. Printed slots over mechanized waveguide have been selected as radiating elements of the array. A combination of printed and mechanized structure has been designed to get a low loss feeding structure and a mechanized waveguide structure is selected to perform the monopulse network.
