Abstract
Various antenna designs that are small and cost effective are disclosed. In one design, the antenna is a bent and folded monopole antenna. In another design, the antenna is a folded and tapped monopole antenna. In yet another design, the antenna is a folded, bent, and tapped monopole antenna. The antennas may be part of a system using two back-to-back symmetric antennas. The antennas may be part of a modem, such as a wireless computer modem or a wireless handset.
Claims34
A folded and tapped monopole antenna.
A bent and folded monopole antenna.
An antenna, comprising:
- a first “L-shaped” section;
- a second “L-shaped section;
- at least one section joining the first “L-shaped” section with the second “L-shaped section;
- and
- a tap connected to the first “L-shaped” section.
An antenna system, comprising:
- a first folded monopole antenna including a first tap a distance from an end of the first folded monopole antenna;
- and
- a second folded monopole antenna including a second tap an equivalent distance from an end of the second folded monopole antenna;
- wherein the first folded monopole antenna and the second folded monopole antenna are approximately positioned about a line of symmetry, and wherein the end of the first folded monopole antenna and the end of the second folded monopole antenna are in close proximity across the line of symmetry, wherein the end of the first folded monopole antenna and the end of the second folded monopole antenna are each configured to couple to ground, and wherein the first tap and the second tap are each configured to receive a signal.
An antenna system, comprising:
- a first bent and folded monopole antenna including a first tap a distance from an end of the first folded monopole antenna;
- and
- a second bent and folded monopole antenna including a second tap the distance from an end of the second folded monopole antenna;
- wherein the first bent and folded monopole antenna and the second bent and folded monopole antenna are approximately positioned about a line of symmetry, and wherein the end of the first bent and folded monopole antenna and the end of the second bent and folded monopole antenna in close proximity across the line of symmetry, wherein the end of the first bent and folded monopole antenna and the end of the second bent and folded monopole antenna are each configured to couple to ground, and wherein the first tap and the second tap are each configured to receive a signal.
A modem, comprising:
- a first bent and folded monopole antenna including a first tap a distance from an end of the first folded monopole antenna;
- and
- a second bent and folded monopole antenna including a second tap the distance from an end of the second folded monopole antenna;
- wherein the first bent and folded monopole antenna and the second bent and folded monopole antenna are approximately positioned about a line of symmetry, and wherein the end of the first bent and folded monopole antenna and the end of the second bent and folded monopole antenna in close proximity across the line of symmetry, wherein the end of the first bent and folded monopole antenna and the end of the second bent and folded monopole antenna are each configured to couple to ground, and wherein the first tap and the second tap are each configured to receive a signal, wherein the first bent and folded monopole antenna and the second bent and folded monopole antenna are printed onto a surface of the modem.
