In this letter, a new dual-mode microstrip bandpass filter (BPF) which is mainly composed of a dual-mode resonator, i.e., meandered loop resonator, with high selection performance is proposed. Compared with the traditional square loop resonator (SLR), meander loop resonator has more advantages in miniaturization. Besides, a Minkowski-like pre-fractal geometry with 1st order iteration embedded at the...
A new dual-mode dual-band bandpass filter (BPF) which is mainly formed by a cross patch resonator based on the second Sierpinski fractal curve geometry is introduced in this article. The different order Sierpinski fractal-based resonators (SFRs) are generated from the cross patch by using an iterative Sierpinski generator method. The small patch which is placed at the corner of the SFR is applied...
