“…The size and spacing of metallic vias are chosen to prevent electromagnetic field leakage at the desired resonant frequency and within the manufacturing limits [16][17][18]. Consequently, using (3), the initial dimensions of the cavity can be determined for a desired resonant frequency with the TM 110 mode and optimized by a full-wave simulator.…”

Abstract-A high-performance multilayer dual-mode filter is developed based on the substrate integrated waveguide circular cavity (SICC) in this paper. The filter is constructed with two circular cavities and each cavity supports two degeneration modes, which can be generated and controlled by the coupling aperture and slot located between layers. Detailed design process is introduced to synthesize an X-band dual-mode dual-layer filter. It not only has the good performances, but also reduces the circuit size much more. Moreover, it can be found that the upper side response of the filter is very steep. Good agreement is obtained between the simulated and measured results of the proposed structure.

“…Moreover, the amount of leakage shows similar dependence on the slot length, which is not included here. This leakage-controllable property facilitates design of the desired radiation-aperture distribution such as Taylor distribution along the leaky-wave antenna so as to obtain high directive beam with very low side-lobe level [15][16][17]. It should be noted that, in the conventional implementation of the CRLH leakywave antennas, the radiation capability is directly associated with the CRLH transmission-line parameters that have to fulfill transmissionline requirements, such as the balanced condition.…”

“…In the ordinary approach that was used to implement these CRLH leaky-wave antennas, the transmission line parameters, such as the interdigital capacitors in the microstrip line or interdigital slots on the top metallization of the SIW, are not only responsible for the radiation efficiency but also for maintaining the balanced condition. This implies that fewer degrees of deign freedom are applicable to engineer the radiation characteristics as desired [15][16][17]. The employment of the newly developed waveguide structure, folded substrate integrated waveguide (FSIW) [18,19], may provide a good solution to realize the artificial CRLH transmission line for radiated-wave applications with a greater degree of design flexibility.…”

Abstract-In this paper, novel composite right/left-handed (CRLH) leaky-wave antennas based on folded substrate-integrated-waveguide (FSIW) structures are proposed. The proposed leaky-wave antennas were realized by periodically loading the radiating slots on the top metallization of the FSIW-based CRLH transmission lines. The structural advantages of the FSIW combined with the unique dispersion characteristics of the CRLH transmission line enable the proposed leaky-wave antennas to present continuous beam-scanning capability from backfire to endfire directions, occupy smaller footprint size, and provide more design flexibility than the conventional CRLH leaky-wave antennas. Two of such CRLH leaky-wave antennas were developed. In addition to the continuous beam scanning, it is found that the radiation efficiency and polarization of the FSIW-based leakywave antennas can be easily tuned by means of the slot size and slot orientation, respectively, indicating their potential for versatile applications. Calculated and experimental results are presented and compared. A good agreement is obtained. To the best of our knowledge, it is the first time that the leaky-wave antenna exploits both of the dispersion behavior of the CRLH transmission lines and the structural benefits of the FSIW configuration.

“…As a matter of fact, compact microwave filters with high performance are required in many communication applications. So, substrate integrated waveguides (SIW) have been proposed [1][2][3][4][5][6] and applied to develop many high-quality components [13][14][15][16][17][18][19]. Furthermore, the SIW provides a promising solution to low cost and low profile, while good performance is maintained.…”

“…Thus, the dual-mode technology [8][9][10][11][12][13][14][15][16][17][18] has been introduced in the design of SIW filter to meet the requirements in size reduction. A dual-mode SIW cavity can support two degenerate modes within one resonant unite, which not only reduces the circuit size more than half but also adds the design flexibility.…”

Abstract-A multilayer dual-mode complementary filter is developed based on substrate integrated circular and elliptic cavity (SICC and SIEC) in this paper. The filter is constructed with two different kinds of cavities, and each cavity supports two degenerate modes, which can be generated and controlled by the coupling aperture and slot located between layers. Detailed design process is introduced to synthesize an X-band dual-mode complementary filter. It not only has good performance, but also reduces the circuit size much more. Moreover, Sharp transition characteristic both in the lower and upper sidebands demonstrates high selectivity of the filter. Good agreement is obtained between the simulated and measured results of the proposed structure.
