IEEE transactions on industrial electronics (1982. Print), 2023
To meet the demand for simultaneously supporting the microwave and millimeter-wave technologies in emerging industrial wireless systems, research on dual-band components with a large frequency ratio has been conducted recently. However, it is challenging

Frequency-Tunable Absorptive Bandpass Filter Using Substrate-Integrated Waveguide Structure
IEEE Transactions on Microwave Theory and Techniques, 2021This work, for the first time, presents an absorptive frequency-tunable substrate-integrated waveguide (SIW) filter. For the filter design, an absorptive bandpass filter prototype tailored to an SIW structure has been formulated.

Comparison of Tunable Microwave Bandpass Filters
2018 11th International Symposium on Communication Systems, Networks & Digital Signal Processing (CSNDSP), 2018The development of software-defined radio and Radio-over-Fiber solutions for the future 5G systems necessitates the availability of small, cost-effective and tunable microwave filters. Possibility of integration is another requirement. As variable capacitance diodes are lossy in the millimeter wave (mmW) region, other solutions are utilized, e.g ...

A tunable bandpass patch filter with varactors
2010 IEEE MTT-S International Microwave Symposium, 2010This paper presents a miniaturized tunable bandpass patch filter using varactors. The filter is conceived with a triple-mode circular patch resonator with four slots, where the varactors were connected. The extracted equivalent model, the varactors assembly configuration and their biasing are presented.

Tunable reflectionless microstrip bandpass filters
2018 IEEE Radio and Wireless Symposium (RWS), 2018A class of frequency-reconfigurable reflectionless microstrip bandpass filters is reported. This RF/microwave device is based on a complementary-duplexer architecture made up of a bandpass-type and a bandstop-type channel with resistive termination. Whereas the bandpass channel defines the transmission profile of the overall filter, the input-signal ...

Voltage tunable bandpass filter
2015 Signal Processing Symposium (SPSympo), 2015A voltage tunable bandpass filter is presented. The filter is realized in microstrip technology using two stepped-impedance resonators. The voltage tuning is provided by means of varactor diodes. The filter has fixed absolute bandwidth of 30 MHz in the frequency range from 375 MHz to 915 MHz. The insertion loss is lower than 5 dB and return loss better
