摘要
常规微带耦合器的定向性比带状线耦合器的定向性差 ,有多种方法可以改善微带耦合器的定向性。本文在分析了 1/4波长微带耦合器接补偿电容时的带宽和定向性的基础上 ,提出了一种高定向性、宽频带微带耦合器的设计方法。
The directivity of microstrip coupler is worse than that of strip line coupler. Many methods can be used to improve this situation. This paper analyses the bandwidth and directivity of λ/4 microstrip directional coupler with capacitive compensation,then a new approach is presented for designing broadband and high-directivity microstrip directional couplers. The results of optimizations and experiments show that the method is feasible.
