Abstract
An antenna apparatus includes a radiator, a first grounding branch, and a second grounding branch. The radiator includes a feed point, a first radiation section, and a second radiation section. The first radiation section and the second radiation section are disposed on two sides of the feed point by a first gap and a second gap. A first ground end is disposed at one end of the first radiation section away from the first gap, and a second ground end is disposed at one end of the second radiation section away from the second gap. The first and second grounding branches intersect with the radiator. A matching circuit is coupled in series in the first grounding branch, and a first high-frequency filter is coupled in series in the second grounding branch.
