“…The proposed principle for generating BABPF prototypes is significant because the same concept can be applied to the analysis and enhancement of more complex antiparallel BPFs [15][16][17][18][19][20][21][22], which have been designed previously by different approximate methods and time consuming EM optimization. The BABPF prototypes are also a foundation for developing prototypes with enhanced characteristics that are more suitable for practical implementation.…”

“…A conclusion that some distinctive characteristics of the filters, such as the number and positions of the transmission and reflection zeroes, are a consequence of their topology, can be reached based on the similar characteristics of BPFs described in [5][6][7][8][9][10][11][12][13][14], distinguished by the authors into different kinds and analyzed and designed by different methods. The correlation between the topology and the electrical characteristics is especially noticeable for BPFs with capacitive coupled resonators [15][16][17][18][19][20][21][22]. The intention of this paper is to explore this correlation and to relate the electrical characteristics of this type of filters to their distinctive topology and the component values.…”

Abstract-This paper introduces a theoretical analysis as well as a design example for bandpass filters (BPF) with a distinctive topology. Based on the analysis of simple two-port symmetrical lossless networks with a parallel structure, a method for obtaining normalized BPF prototypes with desired bandwidths was developed. These prototypes can be scaled to any central frequency and symmetrical real termination in the same way as conventional filters. It is also demonstrated that with a slight modification of the basic BPF prototypes, transmission zeros with controllable frequencies can be introduced in both the lower and the upper stopband region. Such modified prototypes are more convenient for the realization of printed filters than the basic BPF prototypes. The proposed filters have almost identical characteristics in the broad vicinity of the passband region either when composed of ideal lumped elements or of transmission lines (TLs). Due to its simplicity, the proposed concept could be applied for the realization of a printed BPF at a large variety of PCB types, substrates and practical design configurations. A microstrip BPF model is realized for the experimental verification of the presented theory. The measured and theoretical results show excellent agreement, confirming the proposed concept and the exactness of the methodology.

“…It has been used for the measurement of dispersion, phase velocity [1][2][3], dielectric constant [4], discontinuities [5,6] and other special applications [7]. This structure is also used for designing microstrip filters [8][9][10]. The interest of researchers and commercial communication industry engineers to these structures has recently increased due to the application of ferroelectric thin-film substrates, high-temperature superconducting microstrip lines and metamaterials in ring resonator fabrication [11][12][13][14].…”

Abstract-In this paper, full-wave analysis of a microstrip-ring resonator capacitively coupled to Microstrip transmission line is presented. The method of the analysis is based on spectral domain in rectangular coordinate system. Since this coordinate system is not compatible with ring structure, triangular basis functions have been utilized for the current distributions on the ring surface. Applying Galerkin's method in spectral domain, the resonant frequencies of the structure and current distributions on the conductors are calculated and the effects of various parameters are studied. To verify the method of analysis, our results are compared with others and the accuracy of the method has been confirmed.

“…For microwave bandpass filters, compact size and high-performance are highly desirable in wireless communication systems, such as satellite and mobile communication systems [1][2][3][4][5]. Dual-mode resonators have been widely used to realize microwave filters due to their advantages such as small size, low mass, and low loss.…”

Abstract-A new dual-mode microstrip bandpass filter with wide stop-band is presented using the square loop resonator with treeshaped patches attached to the four inner corners of the loop. The mode splitting is realized by introducing a small cut locating at a 45 • offset from its two orthogonal modes. It is shown that the dual-mode filter has a wide stop-band including the first spurious resonance frequency. The center frequency can be tuned. Moreover, the proposed filter has a smaller size compared with conventional dualmode bandpass filters at the same central frequency.
