SYSTEM AND METHOD FOR MOBILE ANTENNA WITH ADJUSTABLE RESONANT FREQUENCIES AND RADIATION PATTERN |
摘要 |
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. |
