When the conductance of sound radiation for IDT is equal to the output conductance for the matching network, the reflection loss and transmission loss can be reduced. 叉指換能器的聲輻射電導等於匹配網路輸出端電導時，可以減小反射損耗和傳輸損耗。
Loading the antennae with matching networks will not only decrease the VSWR at the ports of the receivers, but also reduce the influence of the mutual coupling. 載入匹配網路不但能降低接收機埠的駐波比，還能有效地減弱天線之間互耦的影響，改善系統性能。
