【 摘 要 】

References(10)Cited-By(1)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 13GHz to over 17GHz with gain of 16dBi and relatively low cross-polarization levels of less than -25dB. The 3-dB beam-widths of 36° in the H-plane and 22° in the E-plane have been obtained.
