Abstract: An antenna apparatus includes a grounding plate, a monopole, a first feeding component, and a second feeding component. A slot on the grounding plate includes a first slot and a second slot that interpenetrate each other, the second slot extends from the first slot to an edge of the grounding plate. The monopole includes a first stub and a second stub extending from the first stub to the second slot, the second stub and the second slot form a feeding structure. The first feeding component is electrically coupled to the grounding plate to feed the feeding structure to excite a first radiation mode of the antenna apparatus. The second feeding component is electrically coupled to the second stub to feed the feeding structure to excite a second radiation mode of the antenna apparatus. Polarizations in the two radiation modes are orthogonal.

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.
