Propagation characteristics of strapped coplanar waveguidesHinz, Robert C. 28 September 1992 (has links)
The propagation characteristics of a new coupled fin line structure, with
asymetrical, rectangular, top and bottom housings, is evaluated by using the modal
analysis technique. The boundary Green's function of the structure, relating the surface
currents to the electric fields is derived by using this technique. The propagation
characteristics, i.e. propagation constant and impedances, of the structure are determined
by implementing Galerkin's procedure and the results are presented for a wide range of
possible structure dimensions. A CAD compatible, quasistatic analysis based on
conformal mapping of the rectangular housing structure and known coplanar waveguide
results is also presented. The results of the quasistatic analysis are shown to be in good
agreement with the fullwave simulation at low frequencies. / Graduation date: 1993

10 kW L-Band planar power combinerFourie, Gerhardus Johannes 12 1900 (has links)
Thesis (MScEng (Electrical and Electronic Engineering))--University of Stellenbosch, 2006. / This thesis relates to the design and characterization of a 10 kW L-band power combiner consisting
of 8 input ports. The design is implemented in a non-radial planar transmission line
architecture and operates between 1.2 and 1.4 GHz.
Because of the ultra high power requirements for the combiner, special attention is given to the
power handling capabilities of the transmission lines and the other components involved. Simulated
S-parameter models of connector to stripline transitions and a one to four-way junction,
as well as measured S-parameter models of high power terminations are incorporated in the
final design.
A 10 kW combiner was built and measured at low power only due to time constraints and the
limited availability of high power sources. Satisfactory results were obtained in terms of the
graceful degradation of unit amplifiers, port mismatches and power combining efficiency.

Design of Multi Band Microwave Devices Using Coupled Line Transmission LinesKatakam, Sri 05 1900 (has links)
Multi band technology helps in getting multiple operating frequencies using a single microwave device. This thesis presents the design of dual and tri band microwave devices using coupled transmission line structures. Chapter 2 presents the design of a novel dual band transmission line structure using coupled lines. In chapter 3, Design of a dual band branch line coupler and a dual band Wilkinson power divider are proposed using the novel dual band transmission line structure presented in the previous chapter. In chapter 4, Design of a tri band transmission line structure by extending the dual band structure is presented. The Conclusion and future work are presented in chapter 5.

Analysis of planar multi-conductor multilayered structures by network analog methodMcVeety, Joseph J. 13 August 1999 (has links)
In this thesis the network analog method is used to
analyze various planar multi-conductor structures in
multilayered, lossy dielectric media. The method is
based on an efficient impedance network representation
of the finite difference approximation of Laplace's
equation for the electric potential. Using the network
analog method, the transmission line parameters are
computed for several different uniform stripline
structures in lossless and lossy multilayered
dielectric material. The network analog method is also
applied to several three-dimensional structures
consisting of single and coupled conducting patches of
rectangular shape. Results obtained with the network
analog method for single conducting patches in single
and multilayered lossless dielectric media are in good
agreement with published results based on a variational
approach. Further results presented in this thesis
include the coupling capacitance for coplanar and
multilevel patch configurations in lossless and lossy
multilayered dielectric media. / Graduation date: 2000
