| Abstract: | Two methods for the analysis of slot-array radial-line antennas are presented. A moment method (MM) analysis is performed using a cosine basis function for each slot and the Galerkin method. The analysis can be extended to incorporate thickness of the metal plate supporting the slots. Closed form formulas are also derived to model the slot antenna as a multiport network. This model allows a faster antenna analysis when a large number of slots are present. The multiport model has been validated with the MM analysis in a two-slot case and through the measurements of a more complex antenna problem. © 1996 John Wiley & Sons, Inc. |
