发明名称 ELECTROGRAPHIC POSITION LOCATION APPARATUS
摘要 Antenna devices and apparatuses using the antenna devices are disclosed. In one embodiment, the antenna device includes a first plate structure and a second plate structure. A conductive member is adapted to be capacitively coupled to the first plate structure at a first capacitance and is adapted to be capacitively coupled to the second plate structure at a second capacitance. The conductive member is adapted to transmit a signal based on the first capacitance and the second capacitance.
