Abstract: An antenna apparatus includes a radiator and two feeding branch circuits, where a first feeding branch circuit includes a first feedpoint and a first filter circuit electrically coupled between the first feedpoint and the radiator, and where the first feedpoint is configured to feed a first signal of a first frequency band. A second feeding branch circuit includes a second feedpoint and a second filter circuit electrically coupled between the second feedpoint and the radiator, with the second feedpoint configured to feed a second signal of a second frequency band. The first filter circuit is configured to allow the first signal to pass through and ground the second signal. The second filter circuit is configured to allow the second signal to pass through and ground the first signal.
