Design concept: The conventional ring hybrid coupler, generally known as a ‘rat race coupler’, is a lossless, matched and reciprocal four-port device. The conventional ring shape is not always easy to design, however, and is unfavourable to minimise the circuit size, especially in cases where several couplers are used in a circuit such as ...A new type of hybrid ring coupler (or rat‐race coupler)—the gap‐waveguide ring hybrid has been developed in this work. The advantages of the new gap‐waveguide ring hybrid are low manufacturing cost since the good electrical contact between metal plates is not required, and lower transmission loss compared to microstrip line since there is no dielectric material needed.A directional coupler is a four-port device that uses waveguides to distribute power. A directional coupler is characterized by its coupling factor, isolation, and directivity. The scattering matrix of a directional coupler is the most convenient representation of its behavior in complex systems. Microwave circuits use directional couplers to ...A wideband planar 180 hybrid is proposed for arbitrary power division ratios and implementing cascaded planar structure. In addition, the proposed structure not only has the same function as the conventional ring hybrid, but also has a planar cascade connection when connecting other components because the output ports have same direction. The proposed …
Abstract: In this paper, a filtering hybrid ring coupler is proposed with an ultra-wideband passband and a super wide upper stopband. Both double-sided parallel-strip line swap phase inverter and electromagnetic bandgap structures are used. It takes the area of 0.92 × 0.7 λ g 2 to provide a 110% wide passband centered at 1.55 GHz. Good in-band reflection, port isolation, magnitude and phase ...Jun 16, 2021 · The performance of the ring hybrid coupler SIW with electromagnetic band gap (EBG) was confirmed experi- mentally with a coupling factor of 3.79 dB and 12.5% of bandwidth around 8 GHz and an ... …

Download Free PDF View ...A 180° Hybrid Coupler is a four port device that is used either to equally split an input signal with a 180° phase shift between the ports or to combine two signals that are 180° apart in phase. 180° Hybrid Couplers usually consist of a center conductor ring with a circumference of 1.5 times the wavelength (6 times the quarter wavelength). The hybrid coupler is one of the most fundamental building blocks in microwave and millimeter-wave systems. Ring topology can be often found in the hybrid microwave integrated-circuit design of narrow and broad-band integrated couplers and mixers. In this paper, we propose a new design theory using a phase inverter for systematic size reduction and band broadening of a uniplanar hybrid ring ...
