“…To solve this problem, the zero f uz2 is added by the cascading CSRRs. The equivalent circuit of CSRR is a parallel LC resonator [14], which is a single zero (f uz2 ) structure (Fig. 2(c)).…”

A novel ultra-wideband (UWB) bandpass filter with compact size, improved stopband performance and wider bandwidth is presented in this paper. A new defected microstrip structures resonator (DMSR) is proposed and analyzed theoretically. In order to improve the stopband characteristics, three interdigitated parallel coupled-lines (IPCL) and two complementary split ring resonators (CSRR) are adopted. Finally, a filter prototype is fabricated and measured. The measured results show that the proposed filter achieves a bandwidth of 129% from 2.35 to 10.8 GHz. And the insertion loss is less than 0.5 dB with good return loss.

“…However, RF filters present several problems of spurious responses mainly due to the presence of the second harmonic if such conventional designs are used. Various filters are designed with different methods, in order to obtain wide bandwidth, wide upper stopband, and high selectivity [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21]. Methods using the three-line microstrip coupled structure, split ring resonators (SRRs), multimode resonators, open-ended stubs, transversal signal interaction concepts and defected ground surface have been introduced for the WBPF designs with good wideband responses.…”

Abstract-This paper presents the design, simulation, fabrication and measurement of a wideband bandpass filter with wide stopband performance operating at 3.5 GHz. The proposed filter consists of two parallel coupled lines (T-PCL) centred by T-inverted shape. The location of transmission zeros can be adjusted by varying the physical lengths of T-inverted shape to improve the filter selectivity. The wide bandwidth is achieved through enhanced coupling between the input and the parallel coupled lines. Due to the transmission zeros in the lower and upper stopbands, the filter exhibits good performance including an extremely wide stopband and sharp attenuations near the passband together with low insertion and good return losses in the passband. The filter performance is investigated numerically by using CST-MWS. Finally, the microstrip wideband BPF with minimum insertion losses 0.3 dB, centred at 3.5 GHz with a 3-dB fraction bandwidth of 70% and four transmission zeros is implemented and verified experimentally. In addition, good agreement between the simulated and measured results is achieved.

“…The structure of SRR and CSRR is widely used in band-notched antenna [9][10][11], antenna miniaturization [12], band-pass filter [13], and so on. Nevertheless, up to now few papers for RCS reduction using CSRR have been reported.…”

Abstract-In this paper, a new approach for the radar cross section (RCS) reduction of patch array antenna is proposed. Complementary split-ring resonators (CSRRs) are etched on the ground of the proposed patch antenna array. A conventional 1 × 4 patch antenna array is designed with the central frequency of 5.0 GHz. The monostatic RCS of the patch antenna array with CSRRs can be reduced as much as 14 dB compared to that of the conventional array while maintaining almost the same radiation characters. For the case of ϕ-polarized incident wave, the RCS has been reduced in the angular range of −90 • ≤ θ ≤ +90 • in xoz-plane and this angular range is usually less than ±45 • when using conventional methods of RCS reduction.
