“…Since, the proposed structure is a symmetrical structure with respect to the central dot-dashed line shown in Fig. 1, Therefore, only half of the structure should be analyzed using the even-mode and odd-mode methods [10][11][12][13][14][15][16][17]. The model can be divided into two sections from the symmetry plane, an open circuit for even mode and a short circuit for odd mode, as shown in Figs.…”

A compact and high-rejection ultra-wideband (UWB) microstrip band-pass filter is proposed by using the multi-mode resonator (MMR) technique. The proposed MMR structure is realized by three open stubs-loaded and two short stubs-loaded and a high impedance microstrip line. Five modes, including two odd modes and three even modes could be designed within the UWB band. By resizing the dimensions of the stubs, the resonant modes of the MMR structure are arranged wider bandpass which the passband selectivity with this configuration significantly improved. By this configuration, the even modes can be flexibly controlled, while the odd modes remain the same. The proposed filter has a passband covers 4.1-10.6 GHz and its measured 3 dB fractional bandwidth is about 89%. In order to validate the performance of the proposed technique, the designed UWB band-pass filter is fabricated and the experimental verification is provided. A good agreement has been found between simulation and measurement's results. To our knowledge, the size of the proposed UWB filter is small in comparison with known similar filters.

“…The development of modern communication system requires the microwave components especially filters to have a size that is compact. In the last few years, various types of triple‐mode filters have been realized by planar microstrips or metal cavities . However, the microstrip filters commonly suffer from the high‐conductor loss and low power handling capability.…”

In this letter, a triple-mode bandpass filter based on isosceles right-angled triangular (RAT) resonator with three magnetic walls is proposed. To realize the triplemode filter, the RAT resonator is perturbed by two metalized via-holes around the center. These via-holes form an LC resonant unit with the patch. Also, the via-holes make mode shifting of the TM 010 Z mode while not affecting the TM 110 Z mode in order to form the passband. The proposed filter is fabricated and measured. The center frequency is 5.51 GHz and the fractional bandwidth is 20%. The minimum in-band insertion loss and return loss are measured to be 1.26 dB and 20.5 dB. The measurement results show that the filter has featured both compact size and excellent in-band responses.

“…Then, several types of dual-mode resonator have been introduced, including square-loop resonator [2], stub-loaded resonator [3] and slotline resonator [4]. Recently, there are several triple-mode resonators reported in the literature to design integrated BPFs [5][6][7][8][9][10][11][12][13][14][15][16]. In [5], a compact microstrip filter using a triple-mode stepped impedance resonator (TSIR) is proposed in order to suppress the first spurious passband.…”

A novel triple-mode bandpass filter (BPF) using half-wavelength-resonator-coupled squareloop resonator is developed in this letter. The half wavelength resonator is applied to add an additional path, which increases a pole in the passband and a transmission zero in the stopband. Furthermore, the coupling scheme is used to accurately predict its desired performance. Compared to the conventional square-loop dual-mode filter, higher frequency selectivity and wider bandwidth are achieved. Finally, this filter is designed, fabricated and measured. Good agreement is achieved among the theoretical, simulated and measured results. All of these results validate our design idea.
