  • Patent number: 8866690
    Abstract: This invention provides an antenna structure, especially relates to an antenna structure in hand-held device. The antenna structure of the present invention is formed by a continue transmission line, and forming an annular shape. It is featured that the antenna structure has two end points, the first end point is a floating point, and the second end point connected to a ground. A signal input point is connected to the continue transmission line for inputting an antenna signal into the antenna structure. The signal input point keeps two-thirds of wavelength distance from the second end point. According to present invention, a small antenna structure is provided and fitting in with operation in ultra wide bandwidth frequency, furthermore the multi-frequency signal can be transceived. The antenna structure has lower signal intensity of high order harmonic signals, therefore the structure can reduce the antenna signal interferences with the high order harmonic signals.

  • Patent number: 8847832
    Abstract: The multiple polarization loop antenna includes a circularly polarized loop antenna, which may utilize a loop electrical conductor and two signal feedpoints along the loop electrical conductor separated by one quarter of the length of the loop circumference for a signal feedpoint phase angle input difference of 90 degrees. Each of the signal feedpoints may include a loop discontinuity, so that at least one signal source coupled thereto provides circular polarization from the loop electrical conductor. The circularly polarized loop antenna provides an increase in gain and decrease in size relative to the dipole turnstile. It can provide two orthogonal polarizations from two isolated ports, and the polarizations may be dual linear or dual circular.
