Real-time 2-D spectral-decomposition using a leaky-wave antenna array with dispersive feeding network

An array of leaky-wave antennas (LWA) fed with a dispersive feeding network is proposed to decompose, in real-time, the spectral components of a broadband signal in two dimensions of space. Compared to typical real-time decomposition systems, which are restricted to one-dimensional decomposition, such a two-dimensional system can analyze faster signals and thus provide higher frequency resolution. The operation of the proposed structure is demonstrated using array-factor theory.
