In this work, design optimization and
fabrication of a high performance microstrip dual-band
antenna are presented using Substrate Integrated
Waveguide (SIW) technology with Roger 4350 (εr=3.48
and h=1.52mm). Firstly, the SIW antenna design
is considered as a multi-objective multi-dimensional
optimization problem for a simple microstrip geometry
and its geometrical parameters are optimized efficiently
using Differential Evolutionary Algorithm (DEA) in
the 3D CST Microwave studio environment based on
the gain and return loss characteristics at 12 GHz and
24 GHz. In the second step, for justification of the
proposed design method, the optimally designed dual
band microstrip SIW antenna has been prototyped.
Furthermore, the experimental results are compared with
the performance measures of other counterpart designs
in literature. Thus, based on the obtained results and
comparisons, it can be concluded that the proposed
microstrip SIW antenna model and its optimization
procedure, is a sufficient and low-cost solution for X and
K band radar applications.
