Avaliação da taxa de absorção especifica emitida por antenas de microfita com patch retangular nas frequências de operação das diferentes gerações de celulares

Abstract

The adherence to devices that use radiofrequency to receive and transmit information grows since the 80's when the first cell phone came up. Since then new technologies have been created and perfected to be inserted into the devices. The operation of these devices involves the emission of electromagnetic radiation, to which it is inserted within the non-ionizing range. However, exposure to this type of radiation causes, within the human body, tissue heating in the long run. This work will present four microstrip antennas with rectangular patch that resonate in the same frequency bands as the cellular telephones. It will be simulated along with a 3D mold, which represents the head of an adult man, the antennas to be assessed the Specific Absorption Rate on the head, more specifically in the auricular region by being closer to the apparatus at the time of receiving calls.
