Abstract
An apparatus for a capacitive feed planar inverted-F (PIFA) multi-band antenna is provided. The antenna structure of the present invention typically comprises of a ground element, a main radiating element, having predefined slits and arranged above the ground element, and a capacitive feed element. The capacitive feed element is electrically connected to an antenna feed and is detached from the main radiating and ground elements. By having additional secondary elements, the bandwidth or the number of resonant frequencies of the antenna can be increased without increasing the overall dimensions of the antenna.
