Abstract:
1. An antenna structure, comprising: a circular area, comprising a first region and a second region; a feed point, disposed at a center of the circular area; a first radiator, coupled to the feed point, and circuitously extending in the first region along a radial direction and a circumferential direction of the circular area; and a second radiator, coupled to the feed point, and circuitously extending in the second region along the radial direction and the circumferential direction of the circular area, wherein the antenna structure is adapted to transmit a high band signal and a low band signal, and the first radiator comprises a high band section, wherein a path length of the first radiator is about a quarter of a wavelength of the low band signal, and a path length of the high band section is about one of eight of a wavelength of the high band signal.
