Abstract
The aim of this thesis is to study the junction between
an empty rectangular waveguide and a shielded microstrip in
order to build the scattering model representing this discontinuity.
Such scattering model can be used in many microwave
structures,specially those employing semiconductor devices.In
particular,it may be used in the theoretical investigation of
oscillators,in which the active element (Gunn or IMPATT device)
is embeded in a rectangular waveguide operating below cut-off, ~
where the generated power is being extracted by a shielded mic-
rostrip interfacing the embe~ing waveguide.
The electromagnetic fields in both sides of the junction
have been expanded ove! the normal modes of propagation on each
side, then the fields at the discontinuity interface are matched
to obtain a set of coupled integral equations. A technique,based
on the matrix representation of linear operators has been used
to solve’this set of equations. The results, in the form of reflection
and transmission coefficients, have been used to build
the required scattering model.
The theoretical values of Sll over the whole X-band and
those experimentally obtained were coincident within the accu~
racy of the network analyzer display.
