Abstract :
This paper describe a novel design of dual band monopulse antenna array, which is made of a X-band and a K-band in the same planar radiating surface. The K-band array is the traditional waveguide slot antenna, which is interfaced to the X-band antenna. The simulated and measured radiation patterns at center frequency are both presented. The side-lobe level for the sum pattern of two frequency are all less than -22dB, which have been achieved in the experiment.
