PROBLEM TO BE SOLVED: To prevent deterioration in the characteristic caused, due to an inductive component. SOLUTION: First, second microstrip lines 42, 44 provided on a background metallic plate 10 while being parted via a gap region 60, the first, (second) microstrip line 42 (44) is configured by laminating a 1st (2nd) ground conductor 12 (13), a 1st (2nd) dielectric board 14 (16) and a 1st (2nd) conductor line 46 (48) sequentially. The 1st and 2nd conductor lines 46, 48 are arranged in a straight line. A 1st (2nd) gap 56 (58) extending in a direction (g) orthogonal to an arrangement direction (p) is provided to the 1st (2nd) conductor line 46 (48). Let a wavelength, equivalent to a center frequency of a desired frequency band, be λ, then each distance in the arrangement direction (p) among the 1st (2nd) gaps 56 (58) and the gap region 60 is set to be mλ/2 (where m is an integer), respectively. |
