“…Figure 1(a) shows the structure of the proposed dual-mode BPF, which has been constructed by a hexagonal loop resonator with a capacitive loading structure. The circuit size of the hexagonal loop resonator will be reduced greatly by the capacitive loading structure [31]. The capacitive loading structure is realized by using six identical arms with interdigital fingers inside each arm of the resonator.…”

A novel miniaturized dual-mode bandpass filter (BPF) using hexagonal loop resonator is presented. In order to reduce the circuit size, capacitive loading structure is applied to enhance the self-capacitance and electrical length of the hexagonal loop resonator. The frequency selectivity and out-of-band rejection of the proposed BPF can be improved by the two inherent transmission zeros in each side of the passband. Compared with the conventional hexagonal loop resonator without capacitive loading structure, the size of the proposed resonator is reduced by 46.6%. The simulated and measured results are presented and show good agreement.

“…This is because the SRR is the structure of double rings, so that larger induced current can be excited at resonance, as a result, higher rejection level can be obtained in SRRbased filter [3]. In comparison, a SRR-based singlestage (a pair of SRRs) but non-meandered filter performs ~-10 dB maximal insertion-loss at resonant frequency [6], it clearly displays the improvement due to stronger coupling in meandered structure [4]; some systematic errors (~6% for resonant frequency) exist between simulation and measurement. Moreover, if changed the inter-digital length l but keep fixed sizes s, d, and g [refer Fig.…”

“…They can only be implemented in few filtering configurations. Conventionally, parallelcoupled line or end-coupled line filters design approaches can be used in this case [6]. In order to enhance filter performance, various filter configurations including elliptic or quasi-elliptic response would be desired.…”

In this article, new microstrip slow-wave bandpass filters using open loop resonator loaded with interdigital capacitive fingers is proposed. The filter features not only compact in size, but also exhibits spurious stop-band rejection. Filters of this type with elliptic function and Chebyshev response are demonstrated. There is good agreement between experimental and full-wave electromagnetic (EM) simulation results.

still properly and robustly located by finding a its steepest slope or equivalently a maximum value of its derivative (Figure 4(b)).Figures 5(a) and 5(b) show the results of estimated values of in the case of two samples characterized by ϭ 2 Ϫ 0.5j, with thicknesses 11 mm and 33 mm. These estimations have been performed from combinations of samples of i (such as { 1 , . . . , M }, of which nine are presented on Figure 3) associated to different angles of incidence, all included in the parallelogram of uncertainties ( Figure 3). Studies show that the errors in determination of are lower than 8% for the real permittivity, and 20% for the imaginary permittivity.Concerning the determination of the thickness, the relative errors are estimated to a maximum value of 20% and we have remarked that they increase with the thickness.
