Abstract: An inverted-F antenna includes a ground unit, a radiating unit, a short circuit unit, and an isolation unit. The radiating unit is spaced apart from the ground unit, and includes a feed-in point that is configured to be fed with a radio frequency signal. The short circuit unit is coupled between the ground unit and the radiating unit. The isolation unit is spaced apart from the ground unit and the radiating unit, is coupled to the short circuit unit, and includes a portion that is adjacent to the radiating unit and that projectively overlaps a portion of the radiating unit in a direction toward the ground unit.
