In modern wireless systems, it is essential to incorporate numerous functions into a single component to accomplish cost-effective, lossless, and miniaturized properties. To achieve these facilities, multifunctional devices (MFDs) are necessary. An MFD is an electromagnetic radiating or receiving device that offers additional functions that might comprise multiple bands, reconfiguration, filtering, and active devices. A frequency-reconfigurable radiating device is able to adjust its frequency of operation over a wide bandwidth, which reduces the need for multiple radiating devices for different wireless services. Hence, the price and the dimensions of the wireless system can be minimized.

可重构分形设备


在现代无线系统中，必须将众多功能集成到单个组件中，以实现经济高效、无损和小型化的特性。为了实现这些设施，多功能设备（MFD）是必要的。 MFD 是一种电磁辐射或接收设备，可提供可能包括多个频段、重新配置、滤波和有源设备的附加功能。频率可重构辐射装置能够在较宽的带宽上调整其工作频率，这减少了针对不同无线服务对多个辐射装置的需求。因此，可以最小化无线系统的价格和尺寸。
