PROBLEM TO BE SOLVED: To widen a band, miniaturize a system, and narrow a mounting area in the antenna system having a planar radiation electrode. SOLUTION: The antenna system comprises a planar ground electrode 31, and the planar radiation electrode 32 that is three-dimensionally formed and radiates radio waves, in an electric field generated at a portion to the ground electrode 31 by supplying a signal at a prescribed frequency. The radiation electrode 32 has a refraction section, is formed three-dimensionally, and is in a shape where short circuiting is prevented in the radiation electrode 32. Such a radiation electrode 32 takes a shape formed into a circle, an ellipse, or an oval is three-dimensionally formed. COPYRIGHT: (C)2005,JPO&NCIPI
