金属包层长周期光纤光栅可用于对谐振波长的调谐。
Metal coated long period fiber gratings (LPFG) can be used to change the resonance wavelength.
频率响应也可以由低压微尺寸压控变容器或者变容二极管控制，并且可被例示为与天线模块共存的调谐的谐振匹配滤波器网络。
The frequency response may also be controlled by a low voltage micro sized varicap, or a varactor diode, and instantiated as a tuned, resonant matching filter network residing with the antenna module.
