Quality factor of a transmission line coupled coplanar waveguide resonator
We investigate analytically the coupling of a coplanar waveguide resonator to a coplanar waveguide feedline. Using a conformal mapping technique we obtain an expression for the characteristic mode impedances and coupling coefficients of an asymmetric multi-conductor transmission line. Leading order terms for the external quality factor and frequency shift are calculated. The obtained analytical...
متن کاملFinite Ground Coplanar (FGC) Waveguide:
To solve many of the problems encountered when using conventional coplanar waveguide (CPW) with its semiinfinite ground planes, a new version of coplanar waveguide with electrically narrow ground planes has been developed. This new transmission line which we call Finite Ground Coplanar (FGC) waveguide has several advantages which make it a better transmission line for RF and wireless circuits. ...
متن کاملCoplanar Waveguide-fed RectangularSlotAntennafor Ultra-Wideband Application
This study describes a tunable coplanar waveguide fed (CPW) rectangularslot antenna to work within ultra wide band (UWB) for the future communication systems. This slot antenna of area 30*20mm is designed on a FR4 substrate and its operation was tested in terms of return loss and gain. The developed antenna shows VSWR 2 bandwidth of 800MHz in 0.7-1.51GHzband as well as bandwidth of 6.06GHz in...
متن کاملCAD Modeling of Coplanar Waveguide Interdigital Capacitor
A lumped-element circuit is proposed to model a coplanar waveguide (CPW) interdigital capacitor (IDC). Closed-form expressions suitable for CAD purposes are given for each element in the circuit. The obtained results for the series capacitance are in good agreement with those available in the literature. In addition, the scattering parameters obtained from the circuit model are compared with th...
متن کاملBroadband Coplanar Waveguide - Fed Wide - Slot Antenna
A large bandwidth wide-slot antenna, fed by coplanar waveguide (CPW), is proposed. Experimental investigations and detailed simulations are conducted to understand its behavior and to optimize for broadband operation. The impedance bandwidth, determined by 10-dB return loss of the proposed slot antenna using both measurement and simulation, is about 131% (2.8 to 14GHz). In addition to be small ...
