Filtenna Designed with Defected Ground Structure (DGS) for Ultra-wideband Applications
In microwave imaging applications, filter and antenna are the key components as front-end devices and function independently. Antenna radiates and receives signals to or from nearby scattered objects while filter is used to suppress unwanted signals noise before and after the required bandwidth.
