A printed low profile monopole antenna with stacked structure for UWB applications is proposed. The antenna system has a circular radiating element coupled to a square patch by via hole. The antenna is fabricated on a FR4 substrate and is fed by a 50ohm microstripeline feed. The operation bandwidth of antenna ranges from 3.2GHz to 11GHz with band dispensation from 5GHz to 6.3GHz to provide interference elimination from WLAN bands. The ground plane dimensions are optimized for an improved antenna performance. Via holes facilitate stacked structure and hence achieves wide operation bandwidth.
