“…According to [11,13], the purpose of inserting blind vias inside the SIW is to confine the electric field in the upper layer, thus increasing the effective permittivity and decreasing the cutoff frequency. On the other hand, for a specified periodicity of blind vias, the electric and magnetic fields should be decoupled.…”

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.

“…Yagi antennas fed by SIW and HMSIW have been presented in [9,10], in which high gain and broadband have achieved with a simple structure. Recently, the slow-wave substrate-integrated waveguide (SW-SIW) by a doublelayer substrate with the bottom layer including metallized via-holes connected to the ground has been proposed in [11]. Compared with the classical SIW, the SW-SIW can reduce the longitudinal dimension by more than 40% as the phase velocity is significantly smaller than the SIW structure.…”

A novel planar Yagi antenna printed on a microwave substrate with dielectric constant of 3.55 for Ku band applications has been presented in this paper. The proposed antenna has been fed by the slow-wave half-mode substrate-integrated waveguide and has achieved good characteristics, such as reduced size, high gain, broadband, and low insertion loss. The proposed antenna has been fabricated by Rogers 4350 substrate with lengths of two arms for dipole 0.46 λ 0 . Measured results indicate that the impedance bandwidth (below −10 dB return loss) is from 15.4 GHz to 19.4 GHz with peak gain 7.49 dBi. Both simulations and experiments convince that the proposed antenna could have reliable applications for Ku band wireless communications.

“…Many of research work focused on miniaturizing the SIW, for example in [3] they used the T-Folded SIW, in [4] the HalfMode SIW (HMSIW) was presented, it reduce the size of the SIW into half, in [5] concept of the Slow-Wave SIW (SW-SIW) is used, and optimized by [6], in [7] the Quarter Mode SIW is applied for a circularly polarized microstrip antenna good results were obtained. Nevertheless none of the research papers presented till now did combine the HM-SIW and SW-SIW principles.…”

Here in this paper we present a new miniaturized SIW using two techniques together, the first is the Slow-Wave SIW and the second is the Half-Mode SIW. Combining these two techniques shows that we can miniaturize our SIW with a factor of 70%. Comparing to other published papers we have miniaturized the usual SW-SIW without decreasing the quality factor or increasing losses. Also a model for calculating the effective permittivity of these type of transmission line is proposed.
