• Compare to the normal rectangular waveguide , ridge waveguide has the character of broader bandwidth , smaller dimension , lower equivalent characteristic impedance , etc . because of these merits , it is used more and more widely , such as broadband ridge waveguide filter , broadband direct coupler , diplexer , frequency converter , phase shifter , ridge waveguide slot antenna array , and so on
  与普通矩形波导相比，脊波导具有工作频带宽、尺寸小、等效特性阻抗低等特点。由于脊波导本身的特点，使其得到了越来越多的应用，例如宽带脊波导滤波器、宽带定向耦合器、双工器、变频器、移相器、脊波导缝隙天线阵等等。
