摘要： An embodiment of the present application provides an antenna device. Theantenna device includes a first feeding branch circuit, a second feeding branch circuit, anda radiator connected between the first feeding branch circuit and the second feedingbranch circuit. The first feed branch circuit includes a first feed point and a first filtercircuit electrically connected between the first feed point and the radiator, and the firstfeed point supplies signals in the first frequency band. It is configured to do. The secondfeed branch circuit includes a second feed point and a second filter circuit electricallyconnected between the second feed point and the radiator, the second feed pointsupplies signals in the second frequency band. It is configured to do. The first filter circuit

is configured to pass the signal of the first frequency band and ground the signal of thesecond frequency band. The second filter circuit is configured to pass the signal of thesecond frequency band and ground the signal of the first frequency band. The antennadevice of the present application has a good matching state, has multi-frequencyperformance, widens the antenna bandwidth, and can be adapted to a multi-frequencyterminal. Embodiments of the present application further provide terminals.
