Miniaturization of 4x4 Butler Matrix Using High Slow-Wave Factor Structure
In this paper,a novel slow-wave structure with high slow-wave factor is proposed.The new structure composed of meandered-line structure,low-impedance transmission line and interdigital structure is capable of reducing the circuit size significantly due to its good slow-wave property.A miniaturized 4x4 Butler matrix resonant at 970MHz is designed using the proposed structure.The size of the proposed 4x4 Butler matrix is merely 5.8%of the conventional ones.The measured results of the manufactured are in good agreement with the simulated results.
