Near-field antennas for accumulating radio frequency energy at different respective segments included in one or more channels of a conductive plate
摘要:
Near-field antennas and methods of operating and manufacturing near-field antennas are provided herein. An example near-field antenna for transmitting radio frequency (RF) power transmission signals includes: (i) a conductive plate including one or more channels extending through the conductive place, a respective channel of the one or more channels having first and second segments, and (ii) a feed element configured to direct a plurality of RF power transmission signals towards the conductive plate. At least some of the RF power transmission signals cause an accumulation of RF energy within a near-field distance of the conductive plate. Furthermore, the accumulation of RF energy includes: (i) a first zone of accumulated RF energy at the first segment, and (ii) a second zone of accumulated RF energy at the second segment, the second zone of accumulated RF energy being distinct from the first zone of accumulated RF energy.
