A compact tri-band bandpass filter (BPF) designed using the stub-loaded stepped-impedance resonator (SL-SIR) is presented in this paper. The characteristics of the SIR are firstly studied by using the even-/ odd-mode analysis method. In order to reduce the overall size, a stepped-impedance meander loop resonator is used to design the tri-band BPF. By optimizing the structural parameters, a tri-band...
A new type of wideband band-pass filter based on DGS structure is investigated with simulation in this paper. The filter is based on the SIW structure. In order to obtain advantages of compact structure and good performance, DGS and defected microstrip structure are adopted. The filter has the advantages of small size and easy integration. CST Microwave studio software is used to simulate the proposed...
The modern war played the decisive role of the precision guided weapon, the key lies in the radar seeker, and the core of the radar seeker is in the signal processor. In this paper, the basic principle of the signal processor front-end algorithm is studied. The band pass sampling theorem, digital down conversion, digital filter and digital pulse compression are introduced in this paper. And according...
In this paper, two dual-band microstrip bandpass filters (BPFs) based on the stepped-impedance resonator (SIR) and stub-loaded SIR (SL-SIR) are presented. The characteristics of the SL-SIR are studied by using the even-/odd-mode analysis method. The simulation results show the length of the loaded stub has no influence on the odd-mode resonant frequency, but it can affect the even-mode resonant frequency...
