The structure is designed to operate at the W-band. The T-shaped slot antenna is placed on the back-side of the SIW and fed by a grounded coplanar waveguide (GCPW) transmission line. A transition between the (GCPW) and the SIW is also designed. The simulated results provide that the antenna has a stable gain over the frequency range (98.79-100.56) GHz with a maximum value of around 6 dBi also high radiation efficiency.engW-bandCavity backed-slot antennaGrounded coplanar waveguide (GCPW)Millimeter-wave applicationsconference object10.23919/EuCAP53622.2022.9769223
