Antenna polarization diversity

A computing device comprising:

• a ground plane;
• an antenna element at least partially formed in the ground plane with at least one edge of the ground plane forming a segment of an antenna of the antenna element;
• a radiofrequency feed coupled to drive the antenna element with a radiofrequency signal;
• and
• at least one selector configured to select between a first electrical configuration and a second electrical configuration in the antenna element, wherein the first electrical configuration induces the radiofrequency signal to drive the antenna element to radiate with a polarization predominately in a first direction of propagation and the second electrical configuration induces the radiofrequency signal to drive the antenna element to radiate with a polarization predominately in a second direction of propagation.

One or more tangible processor-readable storage media embodied with instructions for executing on one or more processors and circuits of a computing device a process for switching antenna polarization in an antenna assembly on a ground plane, the process comprising:

• driving an antenna element of the antenna assembly in a first electrical configuration with a radiofrequency signal to radiate with a polarization predominately in a first direction of propagation, the antenna element being at least partially formed in the ground plane, at least one edge of the ground plane forming a segment of an antenna of the antenna element;
• selectively modifying the antenna assembly from the first electrical configuration to a second electrical configuration, responsive to driving the antenna element of the antenna assembly in the first electrical configuration;
• and
• driving the antenna element of the antenna assembly in the second electrical configuration with the radiofrequency signal to radiate with a polarization predominately in a second direction of propagation, responsive to selectively modifying the antenna assembly from the first electrical configuration to the second electrical configuration.
