Abstract: A single feed antenna design is conducted on a radiator of a specific shape (for example, a strip radiator or a slot radiator) to excite a plurality of antenna modes. For example, performing a feed design on a strip radiator may excite a CM wire antenna mode and a DM wire antenna mode. For another example, performing a feed design on a slot radiator may feed a CM slot antenna mode and a DM slot antenna mode. The antenna design may be used to cover a plurality of frequency bands when an antenna is miniaturized.

Abstract: An antenna disposed on a mobile terminal, where the mobile terminal includes a radiation portion and a circuit board, the circuit board includes a lateral side and a grounding layer, and an insulating slot divides the radiation portion into a feed stub and a parasitic stub. A gap is encompassed by the circuit board and the radiation portion. There is a first branch that extends from the feed stub to the gap for feeding the antenna, and there is a second branch that extends from the parasitic stub to the gap and that is electrically connected to a grounding portion. The antenna excites a current loop winding around the gap on the grounding portion, the feed stub, and the parasitic stub.
