PURPOSE: To improve the strength of connection by easily and exactly connecting a feeder line to a position to provide impedance matching by providing a feeding pattern for feeder line connection continuously to a short-circuit conductor and connecting the feeder line to the pattern.
CONSTITUTION: Silver paste is respectively attached on the upper and lower surfaces of a ceramic board 1 by screen printing, a radiating conductor 2a and a ground conductor 2b are formed, and a short-circuit conductor 3 is formed by attaching the silver paste onto the prescribed side surface of this ceramic board 1 with screen printing so as to short-circuit these conductors 2a and 2b. Then, a feeding pattern 7 for connecting a core wire 6a of a coaxial cable wire 6 as the feeder line is provided continuously to the prescribed position of the conductor 3, and the core wire 6 is soldered and connected to a power feeding point 5 of the pattern 7. Thus, the position of power feeding to the conductor 3 can be fixed and the core wire 6a can be exactly connected to the position to provide impedance matching.
