Modes on a Conductor-backed Slotline
This paper reports on an experimental investigation of modes propagating along a conductor-backed slotline: the dominant mode, and the surface leaky mode. The measurement and the numerical experiments performed in the CST Microwave Studio verify theoretical findings of modes obtained by the method of moments applied in the spectral domain. The dispersion characteristic of the dominant mode on t...
متن کاملDesign of Trapezoidal Ring Antenna Using Conductor-backed CPW Structure
Abstract— In this paper, the trapezoidal ring antenna using the conductor-backed CPW is designed and fabricated. The antenna has a broadband characteristic by the coupling effects through inserted the H-shaped parasitic patch. The conductor-backed CPW shows more stable characteristics than the CPW structure when there is occurred the variation between the feed-line and the ground plane in the f...
متن کاملNovel Periodic Structures for a Slotline : Patch Loaded Slotline
In this Letter, a dumbbell-shaped patch loaded slotline(PLS) is proposed. Like the conventional defected ground structure(DGS) for a microstrip line, we show that the proposed PLS can provide a wide bandstop characteristic in some frequency bands with only one or small number of unit cells. Also, the equivalent circuit model for a unit section is derived from the analysis of the field distribut...
متن کاملEffects of Curved Wavefronts on Conductor-Backed Reflection-Only Free-Space Material Characterization Techniques
A true plane wave is often not physically realizable in a laboratory environment. Therefore, wavefront curvature introduces a form of systematic error into Free-space material characterization methods. Free-space material characterization is important to the determination of the electric permittivity and magnetic permeability of conductor-backed and in situ materials. This paper performs an err...
متن کاملCompact Folded Monopole Antenna Excited by a Conductor - Backed Coplanar Waveguide with Vias
© 2013 ETRI Journal, Volume 35, Number 3, June 2013 A compact monopole antenna excited by a conductor-backed coplanar waveguide (CBCPW) is developed for wireless USB dongle applications. The proposed antenna has a compact dimension of 14 mm × 47.4 mm × 3.5 mm, which is suitable for a USB dongle housing. A slotted elliptical patch and a CBCPW with vertical vias are employed to achieve a further ...
