The length (L) of the coupler usually equal to a quarter of wavelength which propagates in material as follow [10, 11]: 𝝀𝝀g = c f × √εr 𝝀𝝀d = λg 4 where f is operating frequency of the coupler, and ɛr isIn this paper, a new 3-dB branch-line coupler using PDMS substrate and Shieldit Super fabric conductive material is presented. The Shieldit Super fabric has low resistance less than 0.1/sq. and resulting in good conductivity. Both the simulated and fabricated coupler circuits demonstrated a 3 ± 1 dB fractional bandwidth (FBW) for the coupling as a result of the microstrip-slot created at the ...

The 180-degree hybrid couplers are also called the "rat race" couplers. Meandering transmission lines of 180 Degree Hybrid couplers maintain the even 180-degree phase relationship between two coupled lines at all frequencies. 180 Degree Hybrid couplers are used to either add up or split equally a signal with a phase difference.A directional coupler designed to split power equally between two ports is called a hybrid coupler. In designing directional couplers for practical bandwidths, computer modeling and attention to design details help minimize causes of signal loss. Four and Three Port Directional Couplers.2. Trophy points. 18. Activity points. 5,064. Hello , in regular quadrature coupler we have on the output two ports which equal in power and 90 phase difference.

With the rapid development of modern wireless communication systems, the desirable miniaturization, multifunctionality strong harmonic suppression, and enhanced bandwidth of the rat-race coupler has generated much interest and continues to be a focus of research. Whether the current rat-race coupler is sufficient to adapt to the future development of microwave systems has become a heated topic.A directional coupler designed to split power equally between two ports is called a hybrid coupler. Directional couplers are most frequently constructed from two coupled transmission lines set close enough together such that energy passing through one is coupled to the other.
