提出了一种基于扩展谐振功率分配器的新型相控阵。该方法消除了传统相控阵系统中单独的功率分配器和移相器的需要，从而大大降低了电路的复杂性和成本。作为原理证明，我们设计、制造并测试了一个使用变容二极管和微带贴片天线的2ghz扩展谐振相控阵。测量的扫描范围为20/声压度/，扩展谐振相控阵馈电的测量效率通常为80%，相当于1 dB的插入损耗。
A novel phased array based on the extended-resonance power-dividing method has been presented. This method eliminates the need for separate power splitter and phase shifters in a conventional phased-array system, resulting in a substantial reduction in circuit complexity and cost. As a proof of principle, a 2-GHz extended-resonance-based phased array using varactor diodes and microstrip patch antennas has been designed, fabricated, and tested. The measured scan range is 20/spl deg/ and the measured efficiency of the extended-resonance phased-array feed is typically 80%, which corresponds to 1 dB of insertion loss.
