A metal horn antenna fed by a co-planner waveguide with ground (CPWG) is designed and fabricated. To integrate and connect other active elements of the system, the CPWG is designed by multi-substrate PCB technology. A transition in the PCB layer concatenating the CPWG and the microstrip line has provided a continuous structure to lead the electric field from RF circuit into the horn. A ridge waveguide is used to widen the bandwidth. The simulated and measured results show that the proposed antenna has a broad impedance bandwidth of 33.1% (from 20.5 to 28.6 GHz) for |S-11|<-10 dB and the radiation patterns also satisfy the requirements over the bandwidth.
