Abstract
An antenna device, in which a dipole antenna (110), a first monopole antenna, and a second monopole antenna are disposed on an insulating board (140), wherein the dipole antenna (110) includes left and right elements connected to a power feeding section (150), and the left and right elements have: first portions extended from the power feeding section in a state of facing each other; and second portions extended from the first portions separately to left and right sides, and the first monopole antenna (120) connects to the power feeding section and extends toward the second portion of the left element in the dipole antenna (110), and the second monopole antenna (130) connects to the power feeding section (150) and extended toward the second portion of the right element of the dipole antenna (110).
Claims8
An antenna device, comprising:
- an insulating board;
- a power feeding section;
- a dipole antenna disposed on the insulating board and configured to receive electric power from the power feeding section;
- a first monopole antenna disposed on the insulating board and configured to receive electric power from the power feeding section;
- and
- a second monopole antenna disposed on the insulating board and configured to receive electric power from the power feeding section, wherein:
- the dipole antenna includes left and right elements connected to the power feeding section, and the left and right elements have:
- first portions extending from the power feeding section in a state of facing each other;
- and
- second portions extending from the first portions separately to left and right sides,
- the first monopole antenna connects to the power feeding section and extends toward the second portion of the left element in the dipole antenna,
- the second monopole antenna connects to the power feeding section and extends toward the second portion of the right element of the dipole antenna, and
- the dipole antenna including the first portions and the second portions, the first monopole antenna, and the second monopole antenna are disposed on a same plane.
A display device, comprising:
- an antenna device including an insulating board, a power feeding section, a dipole antenna, a first monopole antenna, and a second monopole antenna, the dipole, first monopole and second monopole antennas being disposed on the insulating board and configured to receive electric power from the power feeding section;
- a main body housing an electric circuit configured to convert, into an electric signal, a radio wave received by the antenna device;
- and
- a display configured to receive the electric signal from the main body and display an image, wherein:
- the dipole antenna of the antenna device includes left and right elements connected to the power feeding section, and the left and right elements have:
- first portions extending from the power feeding section in a state of facing each other;
- and
- second portions extending from the first portions separately to left and right sides,
- the first monopole antenna connects to the power feeding section, and extends toward the second portion of the left element of the dipole antenna,
- the second monopole antenna connects to the power feeding section extends toward the second portion of the right element of the dipole antenna, and
- the dipole antenna including the first portions and the second portions, the first onopole antenna, and the second monopole antenna are disposed on a same plane.
