RESUMO:

The advances on wireless systems and the growth of their applications in recent years have made the use of compact multiband and broadband antennas very attractive and of great importance for commercial and military systems applications. The most common examples are found in the variety of portable wireless communication devices such as: cell phones, 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 increase the search for compact, lighter and low cost devices, as planar microstrip antennas. The development of antennas with these characteristics is still a challenge to current research. This work aims to study, design, manufacture and measure new geometries of planar antennas with slotted ground planes, aiming at reducing their size, volume and weight, to meet the demands of the services offered by the 5G Mobile Systems and LMDS (Multipoint Local Distribution Service), for example. The numerical analysis will be performed using the Finite Element Method (FEM), implemented in the High Frequency Structure Simulator (HFSS), and equivalent circuits. Preliminary results confirm the functionality of the chosen method, through the good agreement observed between simulated and measured results. Suggestions are presented for the continuity of the proposed work.
