We have designed a magic-T in groove gap waveguide technology which has been introduced to implement low loss microwave component devices without any need to electrical contact between metal layers of the structure.The 180 degree hybrid was desined using three stickers logos dallas cowboys ports in groove waveguide and one waveguide port in the top plate in GGW concept.Using reactive elements we have increased the bandwidth of the proposed structure.A sample is designed and simulated for operation at Ku band.The simulation results rubbermaid 8 gallon trash can show proper sum and difference performances of the proposed structure.
