Abstract
A novel high-performance miniaturized Wi-Fi band-pass filter is proposed in this paper.The high-pass character?istic of SIW and band-stop characteristic and perturbation of slot-line are combined into band-pass filter,loading slot-line DGS on the metal ground plane of SIW.The center frequency of the filter to be designed is 2.45GHz.Its 3dB bandwidth is 0.1798GHz.The insertion loss is better than 0.7968dB and the reflection loss is less than-33.6360dB in the pass-band.It has good out-of-band re?jection.The size of the filter is only 21.9mm by 37.3mm.Simulation results show that the novel Wi-Fi band-pass filter has the ad?vantages of small size,low insertion loss and high out-of-band rejection.关键词
