Conference Paper
In this paper, a novel microstrip balun bandpass filter with tunable center frequency is presented. The proposed structure is constructed by open loop resonators having varactor diodes. The varactor diodes are used to tune the resonant frequency of the resonators. By virtue of coupled open loop resonators with varactor diodes, two bandpass filters...
Conference Paper
This paper presents an electronically tunable filter implementation based on microstrip patch resonator surrounded by an electrical wall to reduce insertion loss of the filter. The dualmode tunable bandpass filter is realized using varactor diode elements. The passband of the filter covers different six states (responses) ranging from 2.0GHz to 2.5...

In this paper, a novel microstrip diplexer with tunable bandwidths and switchable channels is presented by using dual-mode square loop resonators (DMSLRs). Two resonators at different electrical lengths are coupled to input and output ports with lumped capacitors, and the isolation between the output ports is optimized by means of these capacitors....
Article
In this article, a novel dual-mode wideband bandpass filter having tuning stubs is proposed. Proposed filter has two stopbands in the lower and higher sides of the passband as the filter is configured as a bandstop filter by using direct-connected feedlines. Hence, a passband can be created inside a wide stopband by means of the open-circuited stub...
Conference Paper
In this letter, the effect of open-circuited stubs on the frequency response of a microstrip square loop resonator shaped as a meander form is investigated with a full-wave electromagnetic (EM) simulator and a triple-mode microstrip bandstop filter is designed by using this effect. Proposed filter configuration is consisted of a microstrip square l...

In this letter, L-shaped conductor backed asymmetric coplanar stripline (LSCBACPS) and U-shaped conductor backed coplanar waveguide (USCBCPW) branch line coupler fed by microstrip transmission line have been investigated for the miniaturization. The number of interdigital finger unit cells located at the branch and through lines of the conventional...
