Abstract
A system and method for sensing the proximity of an electronic device, in particular, a radio frequency mobile communication device such as a mobile telephone, wireless modem equipped portable computer, or the like to a body employs an antenna capable of altering its impedance for changing the amount of radio frequency electromagnetic energy reflected by the antenna when the antenna is in proximity to the body. The radio frequency electromagnetic energy reflected by the antenna is measured and used for determining proximity of the antenna to the body.
