PURPOSE:To adjust easily the frequency by connecting the ends of the 1st and 2nd strip lines mutually with a flexible metallic plate so as to change a pattern of a metallic plate. CONSTITUTION:A ground conductor 31 is printed to a lower face of a dielectric substrate 32 and the strip conductors 33, 34 are printed on the upper face. A U-shaped metallic conductor 35 is bonded to one end of the line conductors 33, 34. Further, in changing the pattern of the metallic conductor plate 35, i.e., the width and length, coarse adjustment of the resonance frequency is conducted. Then minute adjustment is conducted by bending the metallic conductor plate 35 in the direction of arrow A or B. |
