Desenvolvimento de antena inteligente utilizando varredura de feixe para aplicação WiMax a 5,8 GHz.

Abstract

WiMax is a long distance, high data rate wireless communications technology that operates in millimeter wave frequency bands and allows the use of some performance enhancement techniques such as Adaptive Antenna Systems (AAS). These systems can act in several possible ways, among them is the change in the directivity of an antenna according to the input signal, which allows to provide a maximum power in a certain direction of propagation (beamforming). This work presents the development of the design of a smart antenna with operation in 5.8 GHz composed of a Butler Matrix 4x4 and planar antenna printed on substrate FR4 for the accomplishment of the beamforming technology.
