PROBLEM TO BE SOLVED: To facilitate the adjustment of composite resonance frequencies and impedance adjustment by arranging a ground conductor on one face of the dielectric substrate of a planar antenna and arranging a square patch-like conductor whose lengths of three sides differ on the other face. SOLUTION: The ground conductor is arranged at the back of a dielectric substrate 1c of a micro strip plane antenna 1, a feed pin 1a passes through a through-hole without contacting from the back side and is connected to the feed point H of a patch-like conductor 1b. A crossing point of diagonals EF and BD in a rectangle FBDF is set to be point G and the point H is provided on a segment EG for making a right-handed polarized wave, so as to set it to be the feed point. A side EB in the rectangle EBFD is extended and is set to be the side AB. A side BF is extended and is set to be the side BC. The first side, the second side, the third side and the fourth side of the patch-like conductor 1b are set to be sides AB, BC, CD and DA, and sides CD and DA become oblique lines. Thus, the range of values for which a distance from the point H can take is enlarged. |
