The UWB antenna was achieved using a fat monopole with a microstrip type feed-line. The antenna can be reconfigured to a switchable NB antenna by the use of cascaded complementary split ring resonators within the feed-line. The reconfigurability was based on a frequency-switchable filter embedded in the feed-line. Simulations and measurements demonstrated that the UWB mode operated from 2 to 10 GHz, while being able to switch to multiple NB frequencies. � 2013 IEEE.EnglishOctober University for Modern Sciences and ArtsUniversity for Modern Sciences and ArtsMSA Universityجامعة أكتوبر للعلوم الحديثة والآدابcomplementary split ring resonatorsfiltersreconfigurable antennaUWB antennaComplementary split ring resonatorsMicrostripesNarrow bandsRadio applicationsReconfigurabilityReconfigurable antennaSimulations and measurementsUWB antennaAntennasBroadband networksFilters (for fluids)Optical resonatorsUltra-wideband (UWB)Conference Paperhttps://doi.org/10.1109/LAPC.2013.6711936
