SUMMARY:

In recent years, advances in wireless communication systems and the growth in the number of applications have made it attractive to use compact multiband and broadband antennas for both commercial and military communications. The most common examples are found in the variety of portable wireless communication devices, such as: smartphones, handsets, palmtops and laptops, among others. The development of different wireless technologies, such as GSM (Global System for Mobile Communications), RFID (Radio Frequency Identification), Bluetooth, Wi-Fi and WiMAX, has served as a motivation to boost searches in search of lighter devices , compact and low cost, as is the case of planar microstrip antennas. The development of antennas with these characteristics is still a challenge to current research. This work aims at the study, design, manufacture and measurement of new planar antenna geometries, with openings in the ground plane and the use of FSS (Frequency Selective Surface), aiming to reduce its size, volume and weight as well as gain of antennas, to meet the demands of the services offered by the Mobile Systems 5G, for example. The insertion of air layers between the antenna and the EBG structure was also used aiming at a greater degree of freedom to adjust the resonant frequencies. Computational simulations with the objective of predicting the values of the parameters that characterize the proposed structures were performed through the CST and HFSS 13.0 softwares. Prototypes were manufactured and measured. A good agreement was observed between the simulated and measured results.
