A Novel Design of A Microstrip 3dB Coupler
نویسندگان
چکیده
This paper presents a novel design of branch 3dB coupler, it is designed and simulated by using FR4 substrate at the operating frequency 2.45 GHz in the ISM “Industrial Scientific Medical” band. The design is based on two different models, the T-model and combinationalmodel (Tand π-model) in order to reduce the size and improve the performances. After a theoretical study on the use of open stubs, we present the simulation results of this branch line coupler by using ADS from Agilent technologies and CST Microwave Studio. Good agreement is found between simulated and measured results.

Directional couplers are passive devices which are used as power dividers and combiners in microwave, millimeter and terahertz systems. By the use of substrate integrated waveguides (SIW) for the design of such devices, the advantages of waveguide and printed circuit (PC) technologies are utilized simultaneously, such as low cost, small size, low transmission and radiation losses. In this paper...

متن کاملDesign of a Novel 3 Db Microstrip Backward Wave Coupler Using Defected Ground Structure
In this paper an edge coupled microstrip coupler with defected ground structure is presented. A normally 7 dB coupler designed on Alumina substrate is converted into a 3 dB coupler by cutting single rectangular slot in the ground plane encompassing the two transmission lines. Other properties of backward wave coupler remain the same, except for a tighter coupling. With this method of design opt...
متن کاملCompact Reflectometers for a Wideband Microwave Breast Cancer Detection System
The design of compact wideband microwave reflectometers for the purpose of inclusion in a breast cancer detection system is presented. In this system, a wideband frequency source is used to synthesize a narrow pulse via the step-frequency synthesis method. The reflectometer undertakes measurements in the frequency domain and the collected data is transformed to the time/space domain using IFFT....
متن کاملA novel design for all-optical NAND/NOR/XOR gates based on nonlinear directional coupler
In this paper a novel all-optical logic NAND, NOR and XOR gate based on nonlinear directional coupler theory is demonstrated. We use the identical structure which contains three waveguides, for designing these gates; the only difference however, is the power of inputs light beam. In other words, while a beam with 4 W/μm in power considered as logical one, the output is NAND gate and if a beam w...
