Abstract
A tunable PIFA antenna is disclosed for use with wireless communication devices. In three embodiments of the invention, a movable tuning member constructed of a high-dielectric constant material is selectively moved with respect to the feed and shorting pins of the antenna to vary the frequency response of the antenna. In the fourth embodiment, a slot is molded into the frame of the antenna. The size and position of the slot is varied by the molding tool to vary the frequency response of the antenna.
