A dielectric loaded antipodal curvilinear tapered slot antenna based on substrate integrated waveguide is proposed in this study. High gain, low side lobe level and low reflectance could be obtained by choosing of the length and width of slot correctly. The loaded dielectric slab in front of the slot can result in a narrower beamwidth both in the H ‐plane and in the E ‐plane as a dielectric guiding structure. A two‐dimensional antenna array, formed by a non‐planar four‐way power divider, has a broad bandwidth ranging from 9.5 to 12 GHz and high gains over 12 dBi, which can be widely applied to microwave and millimetre‐wave systems.
