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.
