Abstract :
A loaded antipodal linear tapered slot antenna (ALTSA) with a diamond-shaped slot is presented. The feed system is implemented using a substrate integrated waveguide (SIW), tapered microstrip-to-SIW transition and a horn-shaped via. The proposed antenna exhibits a return loss better than 18 dB over the band of interest (50-70 GHz) with a gain of 16.2 dB at the center frequency. The overall efficiency is 94%. Rectangular corrugation is employed to improve the radiation pattern. The ALTSA and the feed system all have been designed on a single layer substrate, resulting in a low-cost compact antenna which is suitable for 60 GHz wireless applications.
