Antenna structure and wireless communication device employing same

摘要

An antenna structure includes a first antenna, a second antenna, a radio frequency (“RF”) circuit, and a controller. The first antenna includes a first radiating portion and a first feeding portion. The second antenna includes a second radiating portion and a second feeding portion. The second radiating portion is positioned in a first plane that is substantially parallel to a second plane in which the first radiating portion is positioned. The RF circuit is configured to output a first current signal to the first feeding portion and a second current signal to the second feeding portion. The controller is configured to control the RF circuit to adjust phases of the first current signal and the second current signal.

1. An antenna structure comprising:
a printed circuit board; a first antenna, the first antenna comprising a first radiating portion and a first feeding portion; a second antenna, the second antenna comprising a second radiating portion and a second feeding portion, the second radiating portion positioned in a first plane that is substantially parallel to a second plane in which the first radiating portion is positioned, and the second radiating portion positioned across the first radiating portion; a radio frequency (“RF”) circuit, the RF circuit positioned on the printed circuit board and electronically coupled to the first feeding portion and the second feeding portion, the RF circuit configured to output a first current signal to the first feeding portion and a second current signal to the second feeding portion; and a controller, the controller positioned on the printed circuit board and electronically coupled to the RF circuit, wherein the controller is configured to control the RF circuit to adjust phases of the first current signal and the second current signal; wherein the second feeding portion is longer than the first feeding portion, the first radiating portion is positioned between and spaced from the printed circuit board and the second radiating portion.
