Abstract: A continuous long slotted waveguide antenna machined in the curved broad wall of a sectoral waveguide and terminated in a matched load is presented. The coefficient for radiating and the offset from the center line to fhe longitudinal axis of fhe broad wall are deduced and used to design a continuous curved-slot antenna at X-band with a quite satisfactory performance,such as full bandwidth.

Key words: slot antennas, antenna design, broadband, waveguide
