Resumen

La transferencia de energía inalámbrica mediante el acoplamiento inductivo de campo cercano. se ha empleado en una serie de aplicaciones, entre ellas carga inalámbrica de dispositivos electrónicos y la alimentación de dispositivos biomédicos implantados. En estas aplicaciones, la energía se transfiere a través de distancias cortas, que son mucho más pequeñas que la longitud de onda de la operación. En estos sistemas, la eficiencia de la transferencia de potencia del enlace está relacionada de forma inversa con el rango de operación. Este artículo se centra en el diseño y la investigación de un par de antenas de microcinta de iguales dimensiones, una de estas es excitada por un pulso emitido usando GNU Radio software y USRP 2901. El par de dispositivos propuesto consta de dos monopolos con tierra defectuosa los tamaños, de 16 mm × 116 mm, que actúan como transmisor y receptor respectivamente. Los dispositivos se han diseñado, simulado y optimizados utilizando el software CST Microwave Studio. Los resultados de la corriente superficial de los dispositivos acoplados indican una buena densidad de corriente en un rango de distancia de 10 mm a 50 mm.
