This thesis reports the analysis of the rectangular shaped defected ground structure
(RS-DGS) and the application of the structure on some microwave devices. DGS is analyzed
in terms of its superior properties, which enables the designers to easily realize
many kind of microwave devices which are impossible to achieve with the standard applications.
Within the scope of this thesis, the focus is on the rectangular shaped DGS
and its characteristic properties. The basic slow wave and high impedance characteristics
are utilized in the design of some microwave devices. The design is carried on at the two
different frequency bands: X-band and Ka band, centering at 10 GHz and 35 GHz, respectively.
Finally, using the high impedance property and the coupling between the
defects, a wide band 1 : 4 beam forming network is designed and implemented at
10 GHz.
