A wide-bandwidth aperture-coupled microstrip patch antenna (MPA) fed by substrate integrated waveguide (SIW) technology is presented at V-band (60 GHz) to enhance the overall radiation efficiency. The antenna is designed using two different slot configurations with a simulated impedance bandwidth of 22% and gain up to 6.8 dB. Furthermore, the antennas show wideband radiation characteristics. The simulated radiation efficiency is better than 98% within the operating impedance bandwidth.
