“…Unlike symmetrical couplers, a frequency-independent 90°phase difference cannot been obtained for asymmetric coupling structures. [9,10] So, the measured phase difference of 90°is only obtained for the symmetric case around 17.5 GHz.…”

“…With the development of SIW circuits, there have been attempts to integrate SIW with planar transmission lines to build up novel hybrid coupling structures. [9,10] CPW is the kind of planar transmission line which is easy to connect to passive or active device in both series or parallel. Therefore, CPW is increasingly playing greater role in the hybrid microwave integrated circuit (HMIC) and MMIC.…”

“…Comparing with SIW couplers, such hybrid couplers are more compact and more flexible to connect to other components. In [9], the SIW-CPW broad-wall coupling mechanism is developed and a hybrid SIW-CPW broad-wall coupler is exploited. This is the first report about a substrate integrated hybrid guided-wave structure and its application.…”

“…This is the first report about a substrate integrated hybrid guided-wave structure and its application. However, the CPW is centered in the upper SIW broad wall in [9], so the signal of the CPW can be exported only by probe if two ends are used for SIW structure.…”

A forward narrow-wall double-slot 3 dB coupler based on hybrid HSIW/GCPW guided-wave structure, Journal of Electromagnetic Waves and Applications, 28:3, 289-294, Based on a novel hybrid guided-wave structure of half-mode substrate integrated waveguide (HSIW) and ground coplanar waveguide (GCPW), a forward narrow-wall double-slot 3 dB coupler with the center operating frequency of 18 GHz is proposed. The narrow-wall double-slot coupling mechanism between TE 10 mode of SIW and TEM mode of GCPW is studied and efficient coupling is achieved by using triangle-shaped slots. Such coupler takes the advantages of low profile, low insertion loss of HSIW and flexibility of GCPW. The coupler is fabricated and the measured results are in agreement with the simulated ones. A relative bandwidth over 20% is achieved with 0.5 dB amplitude imbalance excited at different ports.

“…It was mentioned in [21] that the proposed slotted SIW transmission line can also support waveguide modes. As a matter of fact, the second mode in this structure is observed as a half-mode SIW, and its cutoff frequency increases with a broader central line.…”

This paper presents an innovative broadband millimeter-wave single balanced diode mixer that makes use of a substrate integrated waveguide (SIW)-based 180 hybrid. It has low conversion loss of less than 10 dB, excellent linearity, and high port-to-port isolations over a wide frequency range of 20 to 26 GHz. The proposed mixer has advantages over previously reported millimeter-wave mixer structures judging from a series of aspects such as cost, ease of fabrication, planar construction, and broadband performance. Furthermore, a receiver front-end that integrates a high-performance SIW slot-array antenna and our proposed mixer is introduced. Based on our proposed receiver front-end structure, a -band wireless communication system with M-ary quadrature amplitude modulation is developed and demonstrated for line-of-sight channels. Excellent overall error vector magnitude performance has been obtained.Index Terms-Balanced mixer, broadband, error vector magnitude (EVM), millimeter-wave, 180 hybrid, phase shifter, receiver front-end, substrate integrated waveguide (SIW).
