Abstract:
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 11L, 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.
