Abstract
An antenna may include a conductive material formed in a pattern on an antenna housing, where one end of the conductive material connects to a ground connection. The antenna may further include a tuning stub, having a length (l0), connected to the conductive material at a distance (d0) from the ground connection, where the distance (d0) tunes a resonance of the antenna.

An antenna, comprising:
- conductive material formed in a pattern on an antenna housing, where one end of the conductive material connects to a ground connection;
- and
- a tuning stub, having a length (l0), connected to the conductive material at a distance (d0) from the ground connection, where the distance (d0) and the length (l0) are adjusted to tune a resonance of the antenna, where the adjustment is neutral to antenna matching or effective two dimensional current flow on the antenna.
An apparatus, comprising:
- a transceiver unit;
- and
- an antenna connected to the transceiver unit and to a ground connection, where the antenna includes a tunable stub, having a length (l0), connected to the antenna at a distance (d0) from the ground connection, where a value of the length (l0) and a value of the distance (d0) affect a high band resonance of the antenna and where the value of the length (l0) and a value of the distance (d0) are neutral to antenna matching or effective two dimensional current flow on the antenna.
A method, comprising:
- forming a conductive material formed in a pattern on an antenna housing, where one end of the conductive material connects to a ground connection;
- and
- forming a tuning stub, having a length (l0) and including an open transmission line, connected to the conductive material at a distance (d0) from the ground connection, where the distance (d0) and length (l0) can be adjusted to tune a high band resonance of the antenna, where the adjustment is neutral to antenna matching or effective two dimensional current flow on the antenna.
