| 摘要 |
A structure of dual symmetrical antennas adopted on a broadband product to operate within 2.0 GHz~5.8 GHz, comprises a PCB, two first trapezoid antennas symmetrically aligned with one of parallel sides thereof on a surface of a PCB, and two second trapezoid antennas symmetrically aligned with each other with one of parallel sides thereof on another surface of the PCB opposite to the first trapezoid antennas, wherein the first trapezoid antennas and the second trapezoid antennas simultaneously enable the broadband product to operate at both a first frequency band and a second frequency band, and the second frequency band overlaps a part of the first frequency band. |
