It also employs four open-loop resonators to selectively target undesirable frequency bands, specifically WLAN (5.2 to 5.8 GHz) and the satellite downlink band (7 to 8 GHz). Experimental results closely align with the simulation, verifying the effectiveness of the open-loop resonators in enhancing rejection.enGeometryMicrowave antennasResonatorsSatellite antennasUltra-wideband (UWB)Article
