Abstract: A near field antenna adapted to an object detecting device, for sensing a plurality of units under test of at least an object under test. The near field antenna comprises a periodic guided-wave structure, a metallic reflection portion and at least two near field magnetic coupling antennas. The periodic guided-wave structure disposed below the object under test has a plurality of conductive units periodically arranged on a first plane. The metallic reflection portion is disposed under the periodic guided-wave structure to form an enclosed space. The near field magnetic coupling antennas are disposed on a second plane parallel to the periodic guided-wave structure, and are located in the enclosed space. The feed point and the ground point of each near field magnetic coupling antenna are fed by a coaxial cable with a feeding direction parallel to the periodically arranged conductive units.

Abstract: An antenna system for mobile communication includes a transportation device and an antenna module installed on the transportation device. The antenna module has a first polarized antenna unit and a second polarized antenna unit. The polarized direction of first polarized antenna unit is perpendicular to the polarized direction of second polarized antenna unit, such that when the transportation device moves along a first direction, the first and the second polarized antenna units are coupling to each other, and each has an 8-shaped radiation pattern. The longitudinal direction of the radiation pattern of the first polarized antenna unit and the longitudinal direction of the radiation pattern of the second polarized antenna unit are parallel to a second direction, and the second direction is not parallel to the first direction. Thus, the instant disclosure provides the antenna system capable of restraining the multipath fading of mobile communication.
