PURPOSE:To enable to match the matching of the strip line and feeding line at a broad frequency range, by forming the power feeding strip line conductor of the slot antenna so that it is located to a position biased to one end from the center of slot and it is orthogonal to the slot. CONSTITUTION:At one side of the dielectric substance board 11, the conductor film 12 is uniformly formed and the slot 13 is formed in the conductor film 12. Further, at another side of the board 11, the conductor film 12 being the ground conductor and the strip line conductor 14 forming the power feeding strip line are formed, and the line 14 is formed so that is it orthogonal to the slot 13 at a biased poisiton to one end from the center of the slot 13. The line conductor 14 is formed with the first strip line conductor 14a and the second strip line conductor 14b folded opposingly with the slot 13 from the tip of the line conductor 14a and the line conductor 14b is acted like the inductance loaded in parallel with the slot 13, allowing the matching between the 50 ohm power feeding line 15 and the power feeding slot line to be broad frequency range. |
