Recommendation for
Future Work:
In the whole research work,
attention was paid to simulate all the structures by commercial EM software Zeland
IE3D. Investigations need to be justified experimentally by VNA and
compared with simulated results.
VNA measured the
return loss performance of the T-lines. The future work can be mentioned in the
following manner.
Results
Validated By Theoretical Modeling
The EBGSs are actually complex
geometries. Theoretical modeling is to be made for rectangular EBGS (as the
results vary with the length and width of rectangle) and dumbbell shaped EBGS.
Other complex designs like dual T-line designs need further research work to
explain the behavior theoretically as well as multiple T-lines need to be
considered.
Development of
Algorithm
Researching proper algorithms for
designing dumbbell shaped EBGS is left for further work as currently there is
no such direct method of calculating correct parameters or correct size of
dumbbell shaped EBGS for designing a filter for a particular pre defined
performance (i.e. for a particular type of dual band performance how a dumbbell
shaped EBGS can be chosen). All, in this paper, are just observation of
performance of a pre-designed dumbbell shaped EBGS.
