A novel microstrip bandpass filter

Microwave and Optical Technology Letters, 2004
AbstractA novel compact microstrip bandpass filter which is realized by combining new slow‐wave effect with dual‐parallel coupling, is proposed. The filter is not only compact in size, but also has low insertion loss and sharp rejection. A demonstration filter is optimally designed and fabricated.

Filtering Microstrip to Waveguide Launcher

2024 IEEE International Microwave Filter Workshop (IMFW)
This paper presents a novel synthesis-based co-design of a filtering microstrip-to-waveguide launcher. The pro- posed design is intended to replace the waveguide low-pass filter generally placed between the common port of the diplexer and the antenna ...

A Microstrip Nonreciprocal Tunable YIG Filter

IEEE Journal of Solid-State Circuits, 1968
A nonreciprocal tunable YIG filter in a microstrip configuration has been constructed which makes use of a novel method of generating a circularly, polarized field in the plane of a microstrip circuit. Nonreciprocities in excess of 40 dB have been obtained at X band with relatively low insertion loss and VSWR.

Narrowband microstrip HTS filter

2016 21st International Conference on Microwave, Radar and Wireless Communications (MIKON), 2016
The new type of narrowband bandpass filter is presented. The design and realization of the filter in microstrip technology is described. The filter has been etched from YBCO thin film deposited on sapphire substrate. The filter has bandwidth of 0.2 %, RL better than 20 dB and a size of 2 inch in diameter.

Optimization of microstrip filters tolerances

The Experience of Designing and Application of CAD Systems in Microelectronics, 2003. CADSM 2003. Proceedings of the 7th International Conference., 2004
The procedure of optimization of microstrip filter tolerances allowing for correlation of member tolerances is proposed. The filters realized on the basis of elements with lumped parameters are considered. The model for calculating tolerances is shaped by mapping transfer functions into the space of interval values.

Coupled microstrip comblines filters

International Journal of RF and Microwave Computer-Aided Engineering, 2007
This paper presents a procedure to design filters using a microstrip combline structure. The combline structure provides a way to reduce the final dimension of the filter. The characteristic impedance and phase constant equations of the combline coupler are derived in terms of impedance and phase constant of the single microstrip coupled lines ...

Improvements of Microstrip Loop Filters

2007 International Workshop on Anti-Counterfeiting, Security and Identification (ASID), 2007
A miniaturized microstrip open-loop filter with dual-mode and defected ground structure is presented in this paper. The proposed filter has the characteristics of wide stopband, reduced size, and high selectivity. The combination of dual-mode and defected ground structure successfully eliminates the nearest two spurious harmonics.

Microstrip Filter with Extended Barrier

2019 Radiation and Scattering of Electromagnetic Waves (RSEMW), 2019
The article describes the method and process of designing a interdigital bandpass filter on two two-stage microstrip resonators. As a result of the design, thanks to the introduction of two steps of different widths into the resonator, it was possible to double the barrier band by suppressing the parasitic bandwidth in the vicinity of the third ...
