Abstract: front page image
(EN) This antenna circuit is provided with: a radiation conductor (10); a matching circuit (30) which is arranged between a feeding port (10F) of the radiation conductor (10) and a feeding circuit (20); and a frequency characteristic adjusting circuit (40) which is connected between a frequency characteristic adjusting port (10C) of the radiation conductor (10) and the grounding, and which comprises a variable reactance circuit (40R). The matching circuit (30) comprises a shunt connected first inductance element (L1); the frequency characteristic adjusting circuit (40) comprises a second inductance element (L2); and the first inductance element (L1) and the second inductance element (L2) are magnetically coupled to each other.
(FR) L'invention concerne un circuit d'antenne pourvu de : un conducteur de rayonnement (10) ; un circuit d'adaptation (30) qui est agencé entre un port d'alimentation (10F) du conducteur de rayonnement (10) et un circuit d'alimentation (20) ; et un circuit d'ajustement de caractéristiques de fréquence (40) qui est connecté entre un port d'ajustement de caractéristiques de fréquence (10C) du conducteur de rayonnement (10) et la mise à la terre, et qui comprend un circuit à réactance variable (40R). Le circuit d'adaptation (30) comprend un premier élément d'inductance (L1) connecté par shunt ; le circuit d'ajustement de caractéristiques de fréquence (40) comprend un second élément d'inductance (L2) ; et le premier élément d'inductance (L1) et le second élément d'inductance (L2) sont couplés magnétiquement l'un à l'autre.
