摘要
A waveguide pathway and a phased-array device utilizing the waveguide pathway are provided. The waveguide pathway comprises a two-dimensional array of homogeneous unit cells. Each unit cell includes a branch point leading to two waveguide branches. Each waveguide branch passes through a positive phase shift element and a negative phase shift element, in series, and with each waveguide branch passing through the two phase shift elements in opposite order relative to the other waveguide branch. Each unit cell additionally includes a convergence point where the two waveguide branches converge. The wavepath grid and the phased-array device are capable of producing output channels with linear, asymmetrical phase distribution but with symmetrical power distribution without employing amplifiers. The phased-array device can be tuned with single-channel or dual-channel control.
