H-plane sectoral filtering horn antenna in PCB substrates using via fences at millimetre-wave

The design procedures and electrical performances of filtering antenna consisting of simply cascaded or embedded bandpass filter into H-plane sectoral horn antenna are investigated in this paper. The waveguide type filter and H-plane sectoral horn antenna have been replaced with considerably sizereduced PCB substrate-type filter and antenna using via fences. The simulation results have been obtained from the commercially available software, CST MWS based on FDTD algorithm.
