Abstract

uma frequência de ressonância da antena perde sintonia quando uma parte de um corpo humano se aproxima ou entra em contato com a antena e consequentemente resulta em perda de eficiência. a antena pode ser sintonizada alterando sua capacitância de carga total, de modo que a capacitância de carga total da antena cai dentro de um intervalo de capacitância de referência de uma capacitância de referência, onde a antena pode operar em ou perto da sua frequência de ressonância operacional predeterminada. um capacitor sintonizável pode ser acoplado à antena para ajustar a capacitância de carga total da antena.
