摘要： A spatial filter is developed for specific absorption rate (SAR) reduction in a wireless device. A conductive element is designed to modify the near field distribution of an antenna operating in a wireless device. This reduces SAR while minimizing degradation of antenna efficiency at one or several frequency bands that the antenna is designed to operate over. Lumped reactance can be designed into the conductive element to generate low pass, band pass, and/or high pass frequency characteristics. Distributed reactance can be designed into the conductive element to replace or to work in conjunction with the lumped reactance. Active components can be designed into the conductive element to provide dynamic tuning of the frequency response of the conductive element.
