Abstract
A printed circuit board-implemented antenna may be used in a smart socket. The printed circuit board implemented-antenna includes a plurality of antenna legs arranged within a rectangular area on a printed circuit board of less than 80 square millimeters with each of the plurality of antenna legs formed using one or more metal layers of the printed circuit board, the plurality of antenna legs arranged to provide a return loss of less then −10 dB at 2.4 GHz. The printed circuit board-implemented antenna may be disposed within the smart socket in such a way as to ensure that there are no packaged electrical components in front of or behind the printed circuit board-implemented antenna.

A printed circuit board implemented antenna, comprising:
- a first antenna leg supported by a printed circuit board, the first antenna leg having a length and a width, with a first end region of the first antenna leg operatively connected to an antenna signal trace of the printed circuit board and a second end region of the first antenna leg extending away from the first end region of the first antenna leg in a first direction;
- a second antenna leg supported by the printed circuit board, the second antenna leg having a length and a width, with a first end region of the second antenna leg connected to the second end region of the first antenna leg, and with a second end region of the second antenna leg extending away from the first end region of the second antenna leg in the first direction, wherein a centerline along the length of the second antenna leg is laterally offset from a centerline along the length of the first antenna leg;
- a third antenna leg supported by the printed circuit board, the third antenna leg having a length and a width, with a first end region of the third antenna leg connected to the second end region of the second antenna leg, and with a second end region of the third antenna leg extending away from the first end region of the third antenna leg in a second direction that is orthogonal to the first direction;
- a fourth antenna leg supported by the printed circuit board, the fourth antenna leg having a length and a width, with a first end region of the fourth antenna leg connected to the second end region of the third antenna leg, and with a second end region of the fourth antenna leg extending away from the first end region of the fourth antenna leg in the first direction;
- a fifth antenna leg supported by the printed circuit board, the fifth antenna leg having a length and a width, with a first end region of the fifth antenna leg connected to the second end region of the first antenna leg, and with a second end region of the fifth antenna leg extending away from the first end region of the fifth antenna leg in the second direction that is orthogonal to the first direction;
- and
- a sixth antenna leg supported by the printed circuit board, the sixth antenna leg having a length and a width, with a first end region of the sixth antenna leg connected to the second end region of the fifth antenna leg, and with a second end region of the sixth antenna leg extending away from the first end region of the sixth antenna leg in a direction opposite to the first direction and operatively connected to a ground plane of the printed circuit board.
