PURPOSE:To execute matching of the impedance by providing a capacitance portion between a feeding part of a patch-like radiator and a contact part of the center conductor of a coaxial line. CONSTITUTION:When an interval of a patch-like radiation conductor 1 and a ground conductor is >= about 5mm, a capacitor component is constituted in a feeding part of the conductor 1 by a circular pipe metallic fixture 7 and a dielectric 8, in order to negate a lead inductance component in the center conductor 5 of a coaxial line 4 for executing a feed to the conductor 1 through the inside of a honeycomb 2. In such a way, by forming a simple structure, matching of the impedance can be executed.
