Abstract
An antenna (100) is provided. The antenna includes: a first ground element (105); a first driven element (110) formed from a planar piece of conductive material, the first driven element being configured to transmit and receive wireless signals, the first driven element including a physical slot (130); a conductive line (135) formed in the physical slot such that the conductive line is separated from the first driven element by a gap (G) filled with non-conductive material, the conductive line having a line impedance that is a function of an effective line width of the conductive line, and an effective gap width of a gap between the conductive line and the first driven element; and a signal line (120) configured to send and receive signals to and from the conductive line.

An antenna, comprising:
- a first ground element;
- a first driven element formed from a planar piece of conductive material, the first driven element being configured to transmit and receive wireless signals, the first driven element including a physical slot;
- a conductive line formed in the physical slot such that the conductive line is separated from the first driven element by a gap filled with non-conductive material, the conductive line having a line impedance that is a function of an effective line width of the conductive line, and an effective gap width of a gap between the conductive line and the first driven element;
- and
- a signal line configured to send and receive signals to and from the conductive line.
An antenna, comprising:
- a first ground element;
- a first driven element configured to transmit and receive wireless signals;
- a second ground element;
- a second driven element configured to transmit and receive wireless signals;
- an insulating layer placed between the first and second ground elements and between the first and second driven elements;
- a conductive line formed in the insulating layer between the first and second driven elements such that the conductive line is separated from the first driven element by a first gap and is separated from the second driven element by a second gap;
- and
- a signal line configured to send and receive signals to and from the conductive line.
An antenna, comprising:
- a first ground element;
- a first driven element formed from a planar piece of conductive material, the first driven element being configured to transmit and receive wireless signals, the first driven element including:
- a first physical slot formed at a first location in the first driven element,
- a second physical slot formed at a second location in the first driven element, and
- a third physical slot formed at a third location in the first driven element;
- a conductive line formed in the first physical slot such that the conductive line is separated from the first driven element by a gap filled with non-conductive material;
- and
- a signal line configured to send and receive signals to and from the conductive line,
- wherein the second and third physical slots are formed in the first driven element to be symmetrical around the first physical slot.
