高选择性陷波超宽带天线设计
Design of highly selective band-notched ultra-wideband antenna
摘要
Abstract
The resonant properties of the interdigital capacitance loading loop resonator ( IDCLLR) and its dual counterpart complimentary interdigital capacitance loading loop resonator (CIDCLLR) are studied . Due to the high capacitance/inductance of the IDCLLR/CIDCLLR , the resonators can generate lower resonant frequencies and narrower resonant bandwidths than many other structures . A compact ultra-wideband ( UWB) antenna with quadruple sharp band-notching characteristics is presented by utilizing IDCLLRs and CIDCLLRs . Measured results show that the proposed antenna has a wide bandwidth from 3 to 11 GHz ( VSWR < 2 ) , with four sharp notched bands centered on 3.5 , 5.2 , 5.8 and 7.5 GHz , respectively , avoiding the elimination of many useful frequencies . Moreover , the presence of IDCLLRs and CIDCLLRs scarcely affects the performance of the UWB antenna at its operating frequencies .关键词
