Antenna structure

摘要

An antenna structure is provided. The antenna structure includes a circular area, a feed point, a first radiator and a second radiator. The circular area includes a first region and a second region. The feed point is disposed at a center of the circular area. The first radiator is coupled to the feed point, and winds outwardly in one direction in the shape of a semicircular arch in the first region. The second radiator is coupled to the feed point, and winds outwardly in an opposite direction to windings of the first radiator in the shape of a semicircular arch in the second region.

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.
