RESUMO:

The objective of this work is to present a study on DGS - Defected Ground Strutures. The DGS is nothing more than a defect, or cut, in the ground plane of an antenna or microstrip line which, depending on the dimensions and position thereof in said ground plane, carries multi-band characteristics or even filter characteristics, to said antennas. Microstrip antennas are one of the biggest innovations in antenna theory and development in recent years. Applications of microstrip antennas, are found, in large scale, in the modern systems of microwaves used in the present time.

The evolution of microwave systems and their integrated circuits coupled with the market's need to develop and use low cost manufacturing antennas has led to the emergence of microstrip antennas that are used in high performance aircraft, spacecraft, satellites and missiles, where size, weight, easy installation and aerodynamic profile are required.

Only in recent years, several new concepts have been applied to distributed micro wave circuits. The DGS then stands out with the implementation of new features for microstrip antennas where the metallic ground plane of a microstrip circuit is intentionally modified to improve the performance of the device.

In this context, the work is structured in the study of DGS using computational modeling to analyze and verify improvements and new possibilities.
