The 60 GHz band is capable of providing high speed communication. In this paper a substrate integrated waveguide (SIW) fed high gain antipodal linear tapered slot antenna (ALTSA) is presented. In order obtain high gain the dielectric loading is applied to the ALTSA in addition to the corrugation structure. Using SIW technology, a highly efficient, compact and low cost planar design is realized. An electromagnetic field simulation tool is used for design and simulation of the antenna. SIW power divider is used for designing 1x4 ALTSA array. To validate the proposed design, prototype is fabricated and measured. The simulated results agree well with the measured values which validates the proposed design. The measured return loss of 1x4 ALTSA array is better than 12 dB over the entire 60 GHz band (57 GHz - 64 GHz). The measured gain of 1x4 ALTSA array is 23.1 ± 0.5 dBi over the 60 GHz band.
