PROBLEM TO BE SOLVED: To solve the problem that optimum impedance matching can not be obtained in each feed radiation element when the power is fed to a plurality of feed radiation elements from a common feed point. SOLUTION: The plurality of feed radiation elements 7 and 8 which have feed electrodes 9 and 10 and radiation electrodes 11 and 12 respectively and also have different resonance frequencies are formed on a dielectric board 6. A stub 4 provided with the common feed point 5 provided on a mounting board 1 for fixing the board 6 on which the feed radiation elements 7 and 8 are provided is provided, the feed electrodes 9 and 10 of the respective feed radiation elements 7 and 8 are connected to respective matching points of the stub 4, and impedance matching is made in each of the feed radiation elements 7 and 8. |
