Design of SIW fed antipodal linearly tapered slot antenna array with hat-shaped dielectric loading for 60 GHz wireless communications

Substrate integrated waveguide (SIW) based antipodal linear tapered slot antenna (ALTSA) with dielectric loading at 60 GHz for wireless communication applications are presented. The hat shaped dielectric loaded ALTSA has gain of 17.29 dB with single element and 19.22 dB was achieved with two elements ALTSA. Both got good radiation efficiency of above 92%. The antennas are designed using Rogers RT/Duroid 6002 material with dielectric constant 2.94 and thickness of 0.254 mm. Ansys HFSS and CST MWS were used for the EM computations.
