<p>PROBLEM TO BE SOLVED: To provide an antenna device that makes it possible to achieve a smaller mounting area and a broader band.SOLUTION: The second end part 2a2 of a dipole element 2a is located on the right or left side of a power feed line 3a and below a first end part 2a1, and is separate from a ground part 4a with a second space D2 between them. The second end part 2b2 of a dipole element 2b is opposite to the side where the second end part 2a2 of the dipole element 2a is arranged, as viewed from a power feed line 3b and below a first end part 2b1, and is separate from a ground part 4b with a third space D3 between them. The point 10a of the ground part 4a, which is separate from the second end part 2a2 of the dipole element 2a with the second space D2 between them, and the point 10b of the ground part 4b, which is separate from the second end part 2b2 of the dipole element 2b with the third space D3 between them, are located higher than the point 10c of the ground part 4b, which is separate from a second end part 3a2 of the power supply line 3a with a first space D1 between them.</p> |
