Abstract: An antenna structure includes a main antenna, a parasitic antenna, a matching circuit and a switching circuit. The main antenna includes a feeding strip and a first radiating strip coupled to the feeding strip. The parasitic antenna includes a grounding strip and a second radiating strip coupled to the grounding strip. The second radiating strip is positioned adjacent to and apart from the first radiating strip, and further configured to electromagnetically couple to and be parasitically fed by the first radiating strip. The parasitic antenna and main antenna cooperatively generate at least one high-frequency resonate mode and a low-frequency resonate mode. The matching circuit is electronically coupled to the feeding strip. The switching circuit is electronically coupled to the matching circuit, and configured to regulate an inductance value of the matching circuit output to the feeding strip, thereby regulating a central frequency of the low-frequency resonate mode.

Abstract: An antenna structure includes a feed section, a ground section, a first radiator, a second radiator, and a third radiator. The first radiator and the second radiator are both connected to the feed section. The third radiator is connected to the ground section. The first radiator defines a first slot. A second slot is defined between the second radiator and the third radiator. The third radiator defines a third slot. The third slot communicates with the second slot. Current is coupled from the first radiator and the second radiator to the third radiator via the first slot, the second slot, and the third slot.

Abstract: The present invention discloses a head-mounted display and a video data processing method thereof. The head-mounted display comprises: a video input module, a distortion processing module and a video output module. The head-mounted display divides each image frame in a video into a plurality of image blocks of symmetry according to a graphic correspondence of a distorted image after a distortion processing, performs a distortion processing of any one of the image blocks, and obtains data of the current image frame after the distortion processing according to the graphic correspondence. By dividing the image frame into blocks, the technical solutions provided by the present invention realize a transmission and processing of image data in the video in a block unit, in substitution of the solution in a frame unit in the prior art, and avoids the problem of limited internal storage space.
