摘要： PROBLEM TO BE SOLVED: To provide an antenna device capable of enhancing the degree of freedom in combination of frequency bands that can be covered.SOLUTION: An antenna device is configured so that low frequency radiation elements and high frequency radiation elements operate, respectively, in a relatively low frequency band and a relatively high frequency band separated from each other. A matching circuit is inserted between a transmission and reception circuit and a branch point. A high frequency variable reactance circuit is inserted between the branch point and the high frequency radiation element. A low frequency variable reactance circuit is inserted between the branch point and the low frequency radiation element. The high frequency variable reactance circuit and low frequency variable reactance circuit are configured to be able to adjust the reactance independently from each other.
