摘要：
A first line stub SB1 and one end of each of two switches SW1 and SW2 are connected to a transmission line 11L at spacings L1, L2 and L3 in order from the input end of the transmission line 11 L, the other ends of the two switches are connected to a second line stub SB2, the first and second line stubs have an open end or short-circuit end, and matching at any of four frequency bands can be selected by combining on and off of the two switches SW1 and SW2.
