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.

Microstrip Patch Filtering Antenna

2023
Nowadays, with the development of wireless communication technology, multifunctional electronic designs are becoming increasingly important. In most electronic designs, the bandpass filter and antenna, which constitute the basic components of the RF front end, are designed separately and connected to each other via the transmission line.

Microstrip broadband band-pass filters

2014 12th International Conference on Actual Problems of Electronics Instrument Engineering (APEIE), 2014
Microstrip broadband band-pass filters based on the multimode resonator are investigated. The use in constructions of the strip conductor in the form of an irregular meander allows to create filters with high frequency selective properties. The good conformance of the calculated data in comparison with the received data on experimentally made microwave

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.

Magnetically Tunable Microstrip Filter Structures

1968 G-MTT International Microwave Symposium, 1968
Tunable filter structures are indispensables preselectors in such systems as ECM receivers and telemetry converters. These new integrated circuit filter structures have a number of distinct advantages over the single crystal YIG preselectors, although the tunable frequency range of the planar devices have not exceeded a half octave.

Electronically tunable microstrip combline filter

Canadian Journal of Electrical and Computer Engineering, 1990
The authors present the design of a fast, electronically tunable microstrip combline filter. Packaged GaAs tuning diodes are employed as the tuning elements. The design incorporates the results of experimental varactor characterization. Thus, the package and mounting parasitic effects are adequately estimated.

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 ...

Microstrip extracted-pole lossy filters

2019
In the chapter, the design of microstrip lossy extracted-pole filters has been described. This type of filter can have both of high selectivity and flat passband. The high selectivity is contributed by using extracted-pole technique and the flat passband is achieved by introducing RCCs in the inline network.

Microstrip spurline band-pass filters

IEEE Antennas and Propagation Society International Symposium. 1999 Digest. Held in conjunction with: USNC/URSI National Radio Science Meeting (Cat. No.99CH37010), 2003
We present two novel spurline band-pass filters employing two and three parallel-coupled microstrip lines along with the approximate design equations. These filters exhibited insertion losses of less than 1 and 1.3 dB and return losses of more than 20 and 15 dB in the pass bands centered near 5 GHz. We obtained a good agreement between the measured and
