Characterization of strip-fed cavity-backed slots Academic Article uri icon


  • The use of strip-fed cavity-backed slots is an attractive approach for compact conformal antenna arrays. This configuration also offers greater potential than traditional designs for additional antenna functions demanded by high-performance system requirements. As with previous approaches, it is desirable to avoid costly, time-consuming empirical design techniques, which in turn requires highly accurate analytic/numerical models. A full-wave integral equation analysis is presented, which by using the dyadic Green's functions for multilayered substrates, models this array element with a high degree of accuracy. Using a previously presented Green's function for a grounded slab, the analysis also accounts for dielectric-covered slots. Comparisons are made with measurements to validate the results.<>
