Super-elliptical waveguide technology for reactively loaded antenna arrays

Abstract

The aim of this paper is to introduce a novel super-elliptical waveguide technology for the design of reactively loaded antenna arrays. The benefits arising from the application of the proposed waveguide geometry based on Lame' equation are described and discussed in detail, with a special focus on the possibility of controlling parasitic coupling level between adjacent waveguiding structures by changing the relevant cross section. This gives us an additional degree of freedom in the design process of reactively loaded arrays.
