Abstract: Embodiments are provided for an efficient antenna design and operation method to adjust or add frequency bands at mobile devices using the available limited antenna size. The embodiments include electrically coupling to the antenna elements at a mobile or radio device a tuning stub or element through a printed circuit board (PCB) or a metal chassis. The PCB is placed between the antenna elements and the tuning stub and is connected to the antenna elements. The tuning stub, e.g., at a corner of the PCB, is connected or disconnected via a switch from the PCB, and hence the antenna elements, to shift the radiation of the antenna at different frequencies and also provide an additional mode of radiation. The tuning stub can also be switched to vary the radiation pattern of the antenna.

Abstract: An apparatus is provided including a first antenna with a top face; a bottom face; and a periphery defined by an upper portion, a lower portion, and a pair of side portions. The first slot comprises a body, a first arm, and a second arm that divides the first antenna into a first portion, a second portion, a third portion, and a fourth portion. The first portion is larger than the third portion, and the third portion is larger than the second portion and the fourth portion. Further, the body of the first slot extends between the side portions of the periphery. Still yet, the first arm and the second arm extend between the body and one of the upper portion and the lower portion of the periphery. A dielectric is positioned in the first slot for providing continuous insulation between the first portion, the second portion, the third portion, and the fourth portion.
