This paper presents a high-gain antipodal linearly tapered slot antenna (LTSA) combined with substrate integrated waveguide (SIW) technique for Ku-band applications. The effects of periodic corrugation on the radiating elements are thoroughly investigated to optimize antenna performance. The periodic corrugation contributes to higher gain as well as and lower sidelobe level. The proposed antenna demonstrates broadband performance for frequency ranges from 13 GHz to over 17 GHz with gain of 16 dBi and relatively low crosspolarization levels of less than -25 dB. The 3-dB beam-widths of 36? in the H-plane and 22? in the E-plane have been obtained.
