RESUMO:

Faced with the broad utilization of wireless communication system and of their application in frequency band WLAN (Wireless Local Area Network), the present work aims to analyze the behavior of microstrip antenna, projected in configurations of structures with resonator ring (SRR), complementary resonators (CSRR) and electromagnetic band gap (EBG). These elements are inserted periodically under the patch in the substrate of antennas and developed for frequency bands WLAN – bands reserved in the development industrial, scientific and medical (2.45 GHz and 5.85 GHz). Thus, the study is based on include elements, that improves the performance of the electromagnetic parameters, to the structure of the microstrip antenna. Posteriorly, applies to the antennas proposals to the metasurface model with cell simplified, so as to provide capability to convert the linearly polarized signals, generated by a microstrip antenna in circularly polarized signals, obeying their range of operation projected. The numerical analysis of the structures is by means of Ansoft HFSS^TM, and to validate these results, the structures will be characterized experimentally.
