“…However, the measured bandwidth performance shows improvement from 1.8 GHz (18.0 %) to 1.9 GHz (19.0 %) compared to the simulated bandwidth. Then, a comparison between achieved results from the proposed dual-layer SIW structure with cross slot coupling design again a verified conventional multilayer transition design proposed by [8] is illustrated in Table 1. The proposed dual-layer SIW structure with cross slot coupling shows a good bandwidth compared to the conventional dual-layer SIW structure with rectangular slot coupling.…”

“…For the transverse rectangular slot in the cross-slot coupling design, the design parameter values are based on [8] and [10], which then optimized using CST software in order to obtain a good transition behavior in term of return loss and resonant frequencies. The optimized values are described as slot length, = 0.36 = 7.0 mm and slot width, = 0.36 = 0.7 mm.…”

“…Then in 2015, a multilayer transition design between SIW to SIW structure is demonstrated by [8] as improvement of [7] in term of compactness and low-cost design solution. The multilayer transition design used two layers SIW structure as a replacement to the bulky traditional waveguide with the same type of slot coupling design but in a different orientation.…”

In this paper, design characteristics of cross slot coupling have been explored and realized in a proposed dual-layer SIW prototype for bandwidth enhancement at 10.0 GHz. The assembled prototype consists of two SMA-microstrip input/output interface with low-loss microstrip-taper via transition and two manually stacked SIW structures electrically connected via a small cross slot coupling design. The proposed dual-layer SIW structure is designed using CST software and fabricated using conventional Printed Circuit Board (PCB) manufacturing process on Rogers 4003 C with = 3.38 and = 0.813 mm. The close agreement between simulated and measured results is observed within a frequency range studied of 9.2 GHz to 11.2 GHz with 19.0 % bandwidth performance. The used of cross slot coupling design in the assembled dual-layer SIW structure indicated 9.0 % bandwidth enhancement compared to the conventional multilayer design with rectangular slot coupling. The assembled dual-layer SIW structure with cross slot coupling design shows potential in several RF applications such as radar and satellite communication.
