OPTIMIZATION OF NFC ANTENNA TO MICROCONTROLLER’S BOARD DIMENSIONS

Abstract

This paper is focused on Near-Field Communication (NFC), which is one of the most popular wireless communication. Although the NFC was developed in recent years, it is inseparable part of the everyday activities. NFC antenna is the key element for the realization of the NFC. This paper deals with the design of the miniaturized NFC antenna. Basic equations for coil inductance calculation, which are necessary for the NFC antenna design are presented as well. This paper also focuses on the influence of the coil’s aspect ratio to its inductance. The aim of this paper was the optimization of the NFC antenna dimensions. NFC antenna dimensions were calculated according to dimension of microcontroller Printed Circuit Board (PCB), so the antenna can be laminated directly to microcontroller PCB.
