“…As far as we know, several kinds of SIW phase shifters have been reported [17,18,19,20,21,22,23,24,25]. A self-compensating SIW phase shifter combining delay line and equal-length unequal-width has been designed and fabricated [see Fig.…”

In this letter, a novel 3-D empty substrate integrated waveguide (ESIW) phase shifter with equal length has been proposed. The vertical transitions have been introduced into 3-D ESIW phase shifter in the propagation path. Based on it, the different total lengths of phase shifters in the propagation path and the equal total lengths of phase shifters in the external structure are compatible. The phase shifter consists of multi-layer PCB: top layer, interlayer, middle layer, ESIW PCB, and bottom layer. The theory and design process of ESIW phase shifter have been explained and discussed in detail. To demonstrate its feasibility, the 3-D ESIW phase shifters with equal external length are designed, manufactured and measured. Final results show that the phase shifts of 45.2°±3.7° and 89.7°±4.7° can be achieved over the entire Ka-band. Besides, the return losses and the insertion losses are better than 12.5 dB, and 1.9 dB, respectively.

“…However, the bandwidths are limited and unsatisfactory. To form a phase shifter with a 15 • phase gradient, several phase channels are introduced based on the SIW resonators loaded with extra metallic posts [6]. Obviously, the phase shifter has the characteristics of narrowband and limited phase range.…”

Abstract-In this paper, an improved broadband substrate integrated waveguide (SIW) phase shifter with embedded air strips is presented. Phase shifter can be generated based on the variable widths of SIW, variable lengths of microstrip line and a row of embedded air strips. The simulated and measured results both show that this kind of SIW phase shifter has excellent performance for a wider bandwidth. Measured results indicate that the proposed SIW phase shifters for the 45 • and 90 • versions have achieved the fractional bandwidths of 59.6% from 10.2 to 18.85 GHz with the accuracy of 2.5 • , and of 62.3% from 9.5 to 18.1 GHz with the accuracy of 5 • , respectively. The return losses are better than 15.8 dB and 14.5 dB for 45 • and 90 • modules, respectively. In addition, the insertion losses are both found to be better than 1.6 dB in the considered band.

“…A number of fixed phase shifters based on SIW technology are reported in the literature. Phase shift was achieved by either varying width or length of SIW [1], [2] and [3], loading SIW resonators with extra metallic posts [4] and [5] or by using stub structure in the design [6]. Some tunable SIW phase shifters have also been presented.…”

A novel low loss, electronically controllable two-layer substrate integrated waveguide (SIW) phase shifter is presented in this letter. Wideband coupling between two layers ensures the wide bandwidth. PIN diodes are used to achieve electronic control of phase shifter. An equivalent circuit model for this device is developed and explained. A compact and low loss five-level digital phase shifter using the proposed structure is designed, fabricated and measured. The simulated results excellently agree with measured results. Including the microstrip-to-SIW transitions, the measured insertion loss is dB over desired frequency band, with an amplitude and phase imbalance of dB , respectively. Return loss performance of better than 15 dB is observed from 10 to 14 GHz, providing a wide relative bandwidth of around 33%. Measured results validate better performance compared to its SIW counterparts.Index Terms-Multilayer, phase shifter, PIN diode, substrate integrated waveguide (SIW).
