Abstract
In accordance with embodiments of the present disclosure, an information handling system may include an enclosure for housing information handling resources of the information handling system, the enclosure having an antenna slot formed therein and formed from a material substantially different from that in which the remainder of the enclosure is formed and a circuit board mechanically coupled to the enclosure and proximate to the antenna slot, the circuit board comprising an antenna electrically coupled at two or more locations to the enclosure so as to form a loop antenna and the antenna positioned such that the antenna at least partially overlaps the antenna slot.
Claims14
An information handling system comprising:
- an enclosure for housing information handling resources of the information handling system, the enclosure being formed from an electrically conductive material and electrically coupled to a ground of a power supply of the information handling system, the enclosure having an antenna slot formed therein from a material substantially different from the electrically conductive material from which the remainder of the enclosure is formed, the antenna slot having a first side and a second, opposite side;
- and
- a circuit board mechanically coupled to the enclosure and proximate to the antenna slot, the circuit board comprising an antenna configured as a loop antenna that includes:
- a first end;
- a second, opposite end;
- and
- a middle portion disposed between the first end and the second end;
- wherein the first end of the antenna is electrically coupled to a signal source on the first side of the antenna slot, the middle portion of the antenna is electrically coupled to the enclosure on the second side of the antenna slot, and the second end of the antenna is electrically coupled to the enclosure on the first side of the antenna slot.
A method comprising:
- providing an enclosure for housing information handling resources of an information handling system, the enclosure being formed from an electrically conductive material and electrically coupled to a ground of a power supply of the information handling system, the enclosure having an antenna slot formed therein from a material substantially different from the electrically conductive material from which the remainder of the enclosure is formed, the antenna slot having a first side and a second, opposite side;
- and
- mechanically coupling a circuit board to the enclosure and proximate to the antenna slot, the circuit board comprising an antenna configured as a loop antenna that includes:
- a first end;
- a second, opposite end;
- and
- a middle portion disposed between the first end and the second end;
- wherein the first end of the antenna is electrically coupled to a signal source on the first side of the antenna slot, the middle portion of the antenna is electrically coupled to the enclosure on the second side of the antenna slot, and the second end of the antenna is electrically coupled to the enclosure on the first side of the antenna slot.
