Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

For a tablet computer or a notebook computer, the WIFI antenna is arranged in the tablet computer or the notebook computer, and the WIFI antenna is limited by the installation structure, so that higher requirements are provided for the design of the WIFI antenna. At present, a plurality of built-in WIFI antennas all adopt unidirectional oscillators, so that no matter how the built-in WIFI antennas are designed and optimized, certain directivity necessarily exists, and therefore the performance of the WIFI antennas used in different directions in use is obviously different, especially weak signal positions. In order to optimize the problem, the consistency of the WIFI antenna performance of the tablet personal computer or the notebook computer in all directions is basically guaranteed, and therefore the microwave board-mounted antenna structure with single-ended excitation and left-right symmetrical distributed oscillators is provided.

Fig. 1 is a schematic diagram of an onboard WIFI antenna, which includes a PCB single-sided substrate 01, on which an omnidirectional antenna is printed, a common reference ground 08 is disposed in the middle of the omnidirectional antenna, two ends of the reference ground are symmetrically provided with a radiation gap a05\ B05 and more than 2 radiation arms connected in series, respectively, two ground wire connection points B06\ a06 are disposed on the reference ground, or a common ground wire connection point 07 is disposed in the middle, and is connected with a ground wire of a radio frequency coaxial feeder line through a wire; the head ends of the first radiation walls of the radiation arms which are symmetrically arranged are connected through a lead, and one of the two first radiation walls is provided with a feeder line connecting terminal and is connected with a signal end of a radio frequency coaxial feeder line. Or both first radiating walls are provided with feed connection terminals a 10/B10. The antenna comprises a first radiation arm A04\ B04, a second radiation arm A03\ B03 and a third radiation arm A02\ B02, wherein the second radiation arm is a serpentine radiation arm. Different impedances can be matched by adjusting the length of the snake-shaped radiation arm, and for further convenient adjustment, connecting welding points B09\ A09 are reserved on two adjacent wires of the snake-shaped radiation arm.
