Abstract

"ANTENA DE ALTA FREQuêNCIA TIPO ALTA IMPEDâNCIA", compreendendo uma antena que não é influenciada por um fator externo quando um corpo humano ou algo semelhante aproxima-se da mesma, permitindo uma alta impedância através da redução de um componente de reactância e aumento de um componente de resistência, pelo qual é possível fabricar um produto de tamanho compacto. A antena inclui módulo de radiofreq³ência (RF) com capacidade de entrada e saída de 50<87>, e circuito de combinação ligado entre a antena e o módulo RF para produzir 50<87> de impedância, tendo um diagrama de Smith numa parte helicoidal de 1/4<sym> de modo que uma antena monopolar de 1/2<sym> seja combinada com um módulo RF de 50<87>."HIGH FREQUENCY ANTENNA TYPE HIGH IMPEDANCE", comprising an antenna that is not influenced by an external factor when a human body or something similar approaches it, allowing a high impedance by reducing a reactance component and increasing an resistance component, by which it is possible to manufacture a compact size product. The antenna includes radio frequency (RF) module with input and output capacity of 50 <87>, and a combination circuit connected between the antenna and the RF module to produce 50 <87> impedance, having a Smith diagram on a helical part 1/4 <sym> so that a 1/2 <sym> monopolar antenna is combined with a 50 <87> RF module.
