Abstract: An antenna apparatus and an electronic device. The antenna apparatus includes a feed source, a transmission line, a first radiator including a first feed point, and a second radiator including a second feed point. The transmission line is electrically connected to the feed source. A second end part of the second radiator is disposed away from the first radiator compared to the first end part of the second radiator, a first gap is formed between the first end part of the first radiator and the first end part of the second radiator, the first end part of the first radiator is a ground end, and the first end part of the second radiator is an open end. The two feed points are electrically connected to the transmission line, and the transmission line input a radio frequency signal in a same frequency band to the two feed points.

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.
