Miniature Dual-Mode Microstrip Filters

open access: yesIEEE Microwave and Wireless Components Letters, 2007
In order to reduce the size of dual-mode microstrip filters by keeping excellent performance, novel filter geometry is proposed. The novel filter includes a dual-mode resonator based on a meander structure. The effect of input/output feed lines located along a straight line on filter response is investigated for the dual-mode filter.

A circuit-theoretic approach to the design of quadruple-mode broadband microstrip patch antennas [PDF]

open access: yes, 2008
A novel method for the design of broadband patch antennas is described. The approach taken is to broadside couple two dual-mode patch antennas, resulting in a quad resonance antenna.

Design of tunable microstrip bandstop filter

open access: yes2016 Asia-Pacific Microwave Conference (APMC), 2016
In this paper, a novel microstrip bandstop filter with tunable center frequency and bandwidth is introduced. A dual-mode square loop resonator and three varactor diodes are used to achieve the tunability operation. The dual-mode square loop resonator is coupled to a straight transmission line that connects input and output ports.

A Reconfigurable Pseudohairpin Filter Based on MEMS Switches

open access: yesSensors, 2022
This work presents a bandpass-reconfigurable planar pseudohairpin filter based on RF-MEMS switches. Hairpin-line structures are preferred to design microstrip filters because this class of filters offers a more compact size, and, in general, hairpin ...

Compact microstrip lowpass filter

open access: yesElectronics Letters, 2004
A novel compact microstrip lowpass filter using the slow-wave resonator is described. This filter has the advantages of low insertion loss in the passband, high and wide rejection in the stopband and compact size. A demonstration filter is designed, fabricated and tested. Theoretical and experimental results are presented.
