Antenna configuration for electronic devices

A device, comprising:

• a chassis;
• a printed circuit board having a ground portion and a dielectric portion, said ground portion being electrically conductive, said dielectric portion being electrically non-conductive;
• an antenna operative to receive wireless signals, said antenna having a first portion, a second portion and a third portion, said first, second and third portions electrically coupled operative to form an F-shaped antenna, said first portion having a first end and a second end, said second portion coupled in orthogonal between said second end of said first portion and said ground portion of said printed circuit board, said third portion coupled in orthogonal to said first portion at a connection point, said connection point being located in the vicinity of said second end between said first and second ends of said first portion, a longitude member of said first portion in-between said connection point and said first end extending along and above said dielectric portion of said printed circuit board in parallel with said dielectric portion of said printed circuit board, said third portion extending between said ground portion and said dielectric portion of said printed circuit board, said third portion being electrically coupled to a signal processor via a reactive element, said reactive element including first and second reactive components coupled electrically in series between said third portion of said antenna and said ground portion of said printed circuit board, said signal processor coupled between said first and second reactive components via a first coupler including a cable coupler;
• and
• a second coupler electrically operative to couple between said ground portion of said printed circuit board and said chassis, said second coupler exhibiting an inherent reactance to said chassis so that said chassis operates as a ground plane for said antenna.
