Abstract:

Multiple interleaved arrays of waveguide radiators have been analyzed at different frequencies. The approach is a generalization of the analysis of an infinite array at a single frequency. The presence of the low-frequency elements affects the radiation characteristics of the high-frequency elements and generates grating lobes which do not appear in a single-frequency array. Furthermore, power is coupled into the low-frequency waveguides when the high-frequency elements are excited. Numerical examples are presented which show that these effects are not severe. The analytical expressions reduce correctly to the single-frequency array case and satisfy the principle of energy conservation. Author
