Serrated waveguide: Theory and experiment

A waveguide with closely spaced transverse slots cut in the broad wall is here named a serrated waveguide for brevity. The slotted portion of the guide is assumed to be fed by a TE01mode. An analysis of the resulting fields in the serrated portion of the guide has been undertaken and the results to date are sketched below. A detailed report of the experiments performed is given. The radiation pattern produced by the fields in the gaps in the serrated wall may be shaped through the use of several control parameters which will be discussed. As an antenna, the serrated waveguide offers flush-mounting, bandwidth, and some versatility in beam shaping through independent control of phase and amplitude over a quasicontinuous aperture.
