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 کاملAnalysis of the Transition between Two Coplanar Waveguide Transmission Lines
Different approaches for the transition between two coplanar waveguides of different characteristic impedances have been investigated to improve the efficiency of both feeding network and the antenna element of an antenna system operating in the Xband. Return loss, effect of feed line shaping and parametric study are presented with each approach. The outcomes of this study leads to efficient tr...

A wideband resonant antenna loaded with coplanar waveguide (CPW) epsilon negative transmission metamaterial line (ENG MTL) unit cells is proposed. The CPW geometry provides high design freedom, and the metamaterial resonant antenna is designed on a CPW single layer where vias are not required. The novel ENG unit cell on a vialess single layer simplifies the fabrication process. The dispersion a...
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 کاملA Novel Broadband Asymmetric Coplanar Waveguide (acpw)-fed Zeroth-order Resona- Tor Antenna Based on Epsilon Negative Transmission Line
A broadband zeroth-order resonant (ZOR) antenna based on asymmetric coplanar waveguide (ACPW) is presented. By adopting the epsilon negative transmission line (ENG-TL), a zeroth-order resonance mode can be achieved. We employ an asymmetric coplanar waveguide structure which offers the design freedom to realize the broadband ZOR antenna, where the antenna’s bandwidth is characterized by the equi...
