摘要: In this research, a compact printed antenna design operating on ultra-wideband (UWB) and three extra wireless communication bands is proposed. An ellipse-shaped monopole utilized to realize UWB application (3.1{10.6GHz). The modifled ground employs folded Capacitive Loaded Line Resonators (CLLRs) obtain triple relatively lower bands, including parts of global System for Mobile Communications (GSM) band at the centre frequency 1.78GHz, Wideband Code Division Multiple Access (WCDMA) 2.15GHz, Wireless Local Area Networks (WLAN) 2.4GHz. CLLRs are designed with quarter- wavelength control corresponding frequencies independently. Good agreement achieved between simulation measurement verify our presented design. basic, dual-, triple-band antennas also simulated good results obtained. Small group delay variations across obtained reference antennas, some level distortion observed.
