| Resumo: | This work presents a theoretical and experimental analysis about the properties
of microstrip antennas with integrated frequency selective surfaces (Frequency
Selective Surface - FSS). The integration occurs through the insertion of the FSS on
ground plane of microstrip patch antenna. This integration aims to improve some
characteristics of the antennas. The FSS using patch-type elements in square unit cells.
Specifically, the simulated results are obtained using the commercial computer
program CST Studio Suite® version 2011. From a standard antenna, designed to operate
in wireless communication systems of IEEE 802.11 a / b / g / n the dimensions of the
FSS are varied to obtain an optimization of some antenna parameters such as impedance
matching and selectivity in the operating bands.
After optimization of the investigated parameters are built two prototypes of
microstrip patch antennas with and without the FSS ground plane. Comparisons are
made of the results with the experimental results by 14 ZVB network analyzer from
Rohde & Schwarz ®. The comparison aims to validate the simulations performed and
show the improvements obtained with the FSS in integrated ground plane antenna. In
the construction of prototypes, we used dielectric substrates of the type of Rogers
Corporation RT-3060 with relative permittivity equal to 10.2 and low loss tangent.
