## Abstract In this letter, a microstrip dualβband bandpass filter (BPF) using novel sideβstubβloaded resonator has been presented.By loading two open stubs at the symmetrical sides of a uniformβimpedance resonator, the center frequency of the fundamental odd mode could be independently controlled
## Abstract In this article, a novel type of compact triβband filter using stubβloaded openβloop ring resonators (OLRRs) is presented.With the open stub loaded, the resonant frequency of the OLRR can be tuned by the tapped location and length of the loaded stub, which makes the OLRR more compact. M
GHz. For this reason, the spacing t was selected to be 1.0 mm for the prototype constructed here. The radiation characteristics of the constructed prototype were also studied. Figures 7 and8 plot the measured radiation patterns at the center frequencies (2442 and 5500 MHz) for the 2.4-GHz and 5.2/5
