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 ...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 ... In this paper, a new dual-band 3dB 180° hybrid ring coupler is presented. The proposed coupler is composed of multiple transmission lines with identical characteristic impedance and electrical length and a dual-band 180° phase shifter. Based on the even-odd analysis, it is found that the proposed coupler can support a wide range of frequency ratio since its realization is mainly limited by ...The hybrid ring coupler, also called the rat-race coupler, is a four-port 3 dB directional coupler consisting of a 3λ/2 ring of transmission line with four lines at the intervals shown in figure 12. Power input at port 1 splits and travels both ways round the ring.
