Antipodal linear tapered slot antenna (ALTSA) for 60 GHz communications is presented in this paper. To obtain a high gain, dielectric loading in addition to the corrugation structure is applied to the ALTSA. The use of substrate integrated waveguide (SIW) technology allows a highly efficient, compact and low cost planar design. The antenna is designed and simulated in an electromagnetic field simulation tool. To validate the proposed design, a prototype has been fabricated and measured. The simulated results agree well with the measured values, which validates the proposed design. The radiation efficiency is observed to be 92%. The antenna has a gain of 18.7 ± 0.5 dBi. The return loss is better than 10 dB over the 60 GHz band (57 GHz – 64 GHz).
