MUTUAL COUPLING REDUCTION BETWEEN PRINTED DUAL-FREQUENCY ANTENNA ARRAYS
摘要： A new defected ground structure (DGS) is designed to reduce the mutual coupling of a dual-frequency printed monopole array. The designed dual-frequency DGS consists of two concentric split ring slots. Each split ring slot produces band rejection characteristics at one resonant frequency of the antennas. An e?ective equivalent circuit model of the DGS section is proposed with the circuit parameters successfully extracted. Good agreement exists among the circuit simulation, EM simulation and experimental results. With the inclusion of the DGS, the measured mutual coupling of the dual-band array has been e?ectively reduced by 10 dB and 20 dB at two resonant frequencies, respectively.

Novel bandpass filter with high selectivity and very wide stopband using open stub loaded and DGS
摘要： A novel bandpass ?lter (BPF) based on half-wave-length (λ/2) stepped-impedance resonators (SIRs) is proposed in this paper. By properly designing the impedance ratios of the SIRs, the spurious harmonics of the ?lter can be pushed to upper frequency. With several bandstop structures such as open stubs and defected ground structures (DGSs) applied to the BPF, a good stopband performance is obtained. Moreover, 0° feed structure is used to improve the selectivity of the BPF. Then a BPF which has high selectivity and wide stopband is implemented. Measured results show good agreement with the simulated results.
