“…In comparison to the conventional waveguide, it not only gives rise to limited bandwidth and high losses in terms of substrate dielectric loss but also contributes to additional metallization losses due to its reduced guided height. Hence, a ridge was introduced to SIW structure in order to enhance operating bandwidth [15][16][17].…”

“…Recently, filters using SIW and RSIW structures loaded with cavity configuration [18], double circular ring [7], triangular ridge [19], slot array antenna [20] and several miniaturized filters structures [12,16,21] have been reported by several authors. The conventional spurious band suppression is mainly designed for the application of single-band rejection [22] of narrow bandwidth.…”

In this research paper, a Ridge Substrate Integrated Waveguide (RSIW) multiple band bandpass filter embedded with an octagonal shape Complementary Split Ring Resonator (CSRRs) is proposed. The electrically coupled octagonal shape CSRR is placed interdigitally in RSIW using transverse coupling technique to improve multiple passband bandwidths. The filter exhibits a highly selective multiple electric or magnetic or bianisotropic mode for different frequencies. The analysis for spurious band suppression has been done by direct method. The prototype configuration of quarterwavelength octagonal CSRR resonators introduces band suppression at all odd harmonics. The proposed structure of filter with dimension 1.36λ g × 0.52λ g excluding feed port is fabricated. Full wave structure simulated results are compared with measurement ones. The measured passband frequencies and their calculated respective central frequency (f 0), fractional bandwidth (FBW) are in close agreement with the simulated result. The spurious higher order harmonics are observed as suppressed. The filter can be utilized to suppress interference from LAN, WLAN, GSM, WiMAX and variable stopband for ISM interference.

Abstract-This paper introduces a novel structure of 4×4 multiple beam forming antenna system using substrate integrated folded waveguide technology. For high speed wireless communication it is necessary to minimize the interferences and multipath fading. Multiple beam forming antenna system is a good solution to these problems. The substrate integrated folded waveguide (SIFW) technology reduces the width of substrate integrated waveguide (SIW) by half. All the basic building blocks required for the antenna array system are designed and simulated individually. They are then combined to form the butler matrix fed antenna array system. The SIFW technology reduces the total width of butler matrix. The radiation performance of the multiple beam forming antenna system is realized by integrating the H-plane SIFW horn antennas with the output ports of the butler matrix. The system is practically realized and good directive multiple beams with symmetric gain (5.8 dB, 5.63 dB, 5.31 dB and 5.9 dB for the beams 1R, 2L, 2R and 1L) have been achieved.

“…Different research works have focused on SIW miniaturization; for example, multilayer SIW technique was applied on a Butler-matrix in [2] and [3] in order to reduce the area by stacking the components on each other. Furthermore, [4][5][6] presented a folded technique for SIW miniaturization, and a 50% of size reduction was demonstrated compared to the conventional SIW.…”

Abstract-Design of a compact Substrate Integrated Waveguide (SIW) transmission line is presented in this paper. The main parameters of SIW were parametrically studied, and final designed component was fabricated and measured, which showed very good matching (near 90%) with simulations, demonstrating significant miniaturization factor. The miniaturization was done using Half-Mode (HM) and Slow-Wave (SW) principles together. It was found that the HM-SW method for SIW miniaturization reduced the SIW surface area with a remarkable factor value (70%) while maintaining acceptable characteristics compared to the original SIW. In fact, HM technique reduced 40% the lateral dimension of the SIW, and using the SW technique allowed 30% of size reduction added to the HM principle. Furthermore, a proper microstrip to HM-SW-SIW tapered transition was designed, which showed a return loss decrease between 3 dB and 7.5 dB, as well as facilitating measurement. On the other hand, the proposed transmission line could lead to a size reduction of 30% compared to the HM-SIW miniaturization technique. The HM-SW-SIW transmission line concept presented in this paper can be used to design other compact SIW components such as bandpass filters, couplers, and power divider.
