<P>PROBLEM TO BE SOLVED: To provide a dipole antenna whose band property is improved considering that the band property of a conventional dipole antenna is not satisfactory since the conventional dipole antenna is provided with only one feeding line including a balun. <P>SOLUTION: The dipole antenna includes: a first dielectric substrate 1 having a dipole 5 print-formed on its one surface and a first feeding line 11 including a balun 11a on the other surface; and a second dielectric substrate 3 having a second feeding line 17 including a balun 17a print-formed on its one surface. The other surface of the second dielectric substrate 3 is connected to the one surface of the first dielectric substrate 1 so that the first feeding line and the second feeding line 17 may be coupled with the dipole 5 through the baluns 11a and 17a included in themselves. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
