Abstract: Embodiments of this application disclose a terminal antenna and an electronic device, and relate to the field of antenna technologies, which can better cover a medium-high frequency band, provide a good bandwidth and good radiation performance, reduce hardware costs, and have a good SAR, thereby better supporting a wireless communication function of the electronic device. A specific solution is as follows: The terminal antenna includes: a first radiator, a feed point, and a ground point. One end of the first radiator is grounded by using the ground point, and the other end of the first radiator is provided with the feed point. The first radiator is further provided with a slot that penetrates the first radiator, the slot is of an interdigital structure, and there are at least two slots.
