Abstract: This application discloses a slot antenna and a terminal. The slot antenna includes a ground plane, an open slot disposed on the ground plane, a slot feeder, and a resonant circuit. The resonant circuit effectively excites a current on a surface of the ground plane, so that the ground plane becomes a primary radiator, and the antenna is a secondary radiator. Therefore, a volume of the antenna can be reduced without affecting radiation efficiency of the antenna.

Abstract: An antenna apparatus includes two feeding parts, a filter matching network, and a radiator. The filter matching network includes a first port, a second port, and a third port. A first feeding part is electrically connected to the first port, a second feeding part is electrically connected to the second port, and the radiator is electrically connected to the third port. The first feeding part is configured to feed a low frequency signal and an intermediate frequency signal, the second feeding part is configured to feed a high frequency signal, the low frequency signal, the intermediate frequency signal, and the high frequency signal are respectively fed into the filter matching network by using the first feeding part and the second feeding part, and the filter matching network is configured to improve isolation between the low frequency signal and the intermediate frequency signal, and the high frequency signal.
