Abstract
A portable communication device uses a first electrostatic antenna element and a second electrostatic antenna element and circuitry which is coupled to the first antenna element and to the second antenna element and which derives operating power from an electrostatic field in the vicinity of the first and second antenna elements. The electrostatic field may be provided by an array of exciter elements containing both horizontal and vertical exciter elements so that at some point as a communication device is moved across the exciter antenna array, the device will have sufficient power coupled to it to power up and become operational.
