摘要：

This paper presents a monopulse substrate integrated waveguide (SIW) collinear slot antenna array at X-band. The collinear slot structure is realized by alternately moving the waveguide wall corresponding to each slot to disturb the electric field inside the waveguide, which effectively reduces the cross-polarization. As for the design of the monopulse feeding network, different from the traditional magic-T structure, this paper realizes the transformation of the sum-difference beam through the microstrip slot coupling feeding structure, which reduces the volume and profile of the antenna. This type of monopulse antenna features low cross-polarization, low profile, easy integration, wideband, and high gain performance.
