摘要：
This paper presents a design of nose-cone conformal substrate integrated waveguide slot antenna array for radar applications. To increase the target tracking azimuth coverage, a novel two beam antenna system is presented with two conformal slot arrays of 1x6 elements. A novel feeding structure is introduced with the rectangular waveguide based power divider. The longitudinal slot elements of both arrays are projected on nose-cone in a mutual alternate fashion. The proposed arrays are simulated in Ansys HFSS, and it is observed that they are resonating at 10 GHz with VSWR <= 2. It is also observed that the proposed array offer reduced side lobe levels (SLLs) having values -20.3 dB and -16.45 dB, respectively, with main beams positions at theta = +/- 90 degrees.
