US 2009/0156191 A1 · COMPUTING DEVICE WITH CONFIGURABLE ANTENNA

Abstract

A computing device with a configurable antenna. The antenna is configured through a switching circuit operating under software control. Operating characteristics of the antenna are configured based on connections between conducting segments established by the switching circuit, allowing the nominal frequency, bandwidth or other characteristics of the antenna to be configured. Because the switching is software controlled, the configurable antenna may be integrated with a software defined radio. The radio and antenna can be reconfigured to support communication according to different wireless technologies at different times or to interleave packets according to different wireless technologies to support concurrent sessions using different wireless technologies.

Dependent claims

A computing device comprising:

a radio having a transmit and/or receive port adapted and configured for passing an electromagnetic signal for wireless communication;
a plurality of antenna elements;
and
a switching circuit coupled to the transmit and/or receive port and each of the plurality of antenna elements, the switching circuit having a control input and being adapted and configured to selectively couple the transmit and/or receive port to one or more of the antenna elements in response to a value at the control input.
