PROBLEM TO BE SOLVED: To provide an antenna that exhibits superior VSWR characteristics and proper directivity over a wide frequency band.SOLUTION: A flake surface shaped antenna element 1 including three or more conductive materials is disposed by allowing the same to be not only rotationally symmetric at around a point C but is also adjacent to each other with a minute gap portion 3. The flake-surface shaped antenna element 1 includes an utmost outer corner portion 10 at a position which is most distant from the point C and a radial slit 2 moving from the point C to the utmost outer corner portion 10, and further, an inner end of the radial slit 2 is continuous up to an end of the minute gap portion 3. |
