Television receiver and electronic apparatus
View Patent ↗According to one embodiment, an electronic apparatus includes a housing having a conductive portion in at least a part of the housing, a component which is accommodated in the housing and emits noise, an antenna which overlaps the component in a thickness direction of the housing, and a conductive member which electrically connects a ground of the antenna and the conductive portion of the housing.
1. A television receiver comprising:
a housing comprising a conductive portion in at least a part of the housing;
a cable in the housing configured to emit noise;
a display in the housing;
an antenna comprising a ground plate and an antenna element connected to the ground plate, the ground plate and the antenna element being formed integrally, the antenna overlapping the cable and at least a part of the display in a thickness direction of the housing;
a conductive member which is bent to skirt the display, and comprises a first portion between the antenna and the part of the display, and a second portion facing the display from a side opposite to the first portion and contacting an inner surface of the housing, the conductive member electrically connecting the ground plate and the conductive portion;
a first support portion between the antenna and the part of the display; and
a second support portion facing the antenna from a side opposite to the first support portion, and configured to hold the antenna as the ground plate is sandwiched between the first support portion and the second support portion, wherein:
the antenna element comprises a folded portion, an outward path, a return path extending substantially parallel to the outward path, and a grounding portion which connects between the outward path and the ground plate, a width of the grounding portion taken in a direction perpendicular to a direction of a width of the outward path taken in a direction perpendicular to a flow of current in the outward path being greater than or substantially equal to the width of the outward path;
the first portion is mounted on a surface of the first support portion facing the ground plate, the conductive member contacting the ground plate as the ground plate is arranged between the first support portion and the second support portion;
the cable is within the bent conductive member;
the ground plate comprises a first convex portion protruding toward the first portion of the conductive member and contacting the conductive member; and
the first support portion comprises a second convex portion protruding toward the ground plate and raising a part of the first portion toward the ground plate.
2. An electronic apparatus comprising:
a housing comprising a conductive portion in at least a part of the housing;
a cable in the housing configured to emit noise;
an antenna overlapping the cable in a thickness direction of the housing, and comprising a ground plate and an antenna element connected to the ground plate, the antenna element comprises a folded portion, an outward path, a return path extending substantially parallel to the outward path, and a grounding portion which connects between the outward path and the ground plate, a width of the grounding portion taken in a direction perpendicular to a direction of a width of the outward path taken in a direction perpendicular to a flow of current in the outward path being greater than or substantially equal to the width of the outward path;
a conductive member configured to electrically connect a ground of the antenna and the conductive portion;
a pair of hinges configured to rotatably connect the housing and another housing; and
a circuit board in the housing,
wherein the antenna is between the pair of hinges,
the conductive member is a conducive sheet extending between the antenna and an inner surface of the housing,
the antenna overlaps at least a part of the circuit board in the thickness direction of the housing; and
the conductive sheet is bent to skirt the circuit board, and comprises a first portion between the antenna and the part of the circuit board, and a second portion facing the circuit board from a side opposite to the first portion and contacting the inner surface of the housing.
3. The electronic apparatus of claim 2 , wherein the cable is within the bent conductive sheet.
4. The electronic apparatus of claim 2 , further comprising:
a first support portion between the antenna and the part of the circuit board; and
a second support portion facing the antenna from a side opposite to the first support portion,
wherein the antenna is held as a part of the antenna is sandwiched between the first support portion and the second support portion.
5. The electronic apparatus of claim 4 , wherein:
the ground plate and the antenna element being formed integrally; and
the antenna is held as the ground plate is sandwiched between the first support portion and the second support portion.
6. The electronic apparatus of claim 5 , wherein:
the first portion is on a surface of the first support portion facing the ground plate; and
the conductive sheet contacts the ground plate as the ground plate is arranged between the first support portion and the second support portion.
7. The electronic apparatus of claim 5 , wherein the ground plate comprises a first convex portion protruding toward the first portion and contacting the conductive sheet.
8. The electronic apparatus of claim 7 , wherein the first support portion comprises a second convex portion protruding toward the ground plate and raising a part of the first portion toward the ground plate.
