A high efficiency Ku-band printed monopulse array

A Ku-band microstrip monopulse array design and performance is discussed in the following paper, wherein 32% antenna efficiency is achieved at higher end Ku-band frequency. The printed array is realized on a single layer of low loss dielectric material. The monopulse comparator, series power divider and array design is described in brief. The design has been carried out using a combination of moment method in spectral domain and array theory. The measured results shows a very well defined azimuth and elevation difference patterns and the results are highly repeatable.
