| Abstract: | The leaky-waveguide traveling wave antenna of the closely spaced transverse nonresonant slots cut in the broad face of a rectangular waveguide. the standing wave array composedof the traveling wave antenna. and whose backscattering RCS are desribled. The antenna examples in Ku-band are given, the results of experimental measured are shown to be batterfeatures of the radiation pattern.gain.input VSWR, bandwidth and RCS. |
