Monopole antenna 40 of the present invention is formed of ground plane 1, flat conductor 10 faced to ground plane 1 and separated from it by clearance "H", and linear conductor 3 that is connected to flat conductor 10, extended on the ground plane 1 side in an insulated state from ground plane 1, and connected to a signal source. Flat conductor 10 is formed of inner conductor 11, and outer conductors 12 and 13 disposed on the outer periphery of inner conductor 11 at a predetermined interval. Set regions of the outer edge of inner conductor 11 and the inner edges of outer conductors 12 and 13 are interconnected through one or more coupling conductors 311, 312, 321 and 322. <IMAGE> |
