PURPOSE:To obtain the wide-band characteristics without increasing the overall structure so much by securing such constitution that the end part of the conductor substrate may rise up at the side of the strip conductor. CONSTITUTION:Part of the end part of dielectric substrate 21 is removed, and conductor substrate 31 is bent toward strip conductor 1 there. At the same time, substrate 21, 31 and conductor 1 are protected with protective cover 4 composed of the wave transmissible material. In such way, the wide-band characteristics equivalent to that obtained via wide-width substrate 31 even if part of substrate 21 is deleted along with the fixed impedance. |
