  • ANTENNA STRUCTURE AND MULTI-BEAM ANTENNA ARRAY USING THE SAME
    Publication number: 20120139805
    Abstract: An antenna structure comprises a substrate, a first antenna unit and a second antenna unit. The substrate comprises a first surface and a second surface opposing the first surface. The first antenna unit is disposed on the first surface, and comprises at least a first slot with a wider inside and narrower outside at the edge of the first antenna unit. The second antenna unit is disposed on the second surface, and is connected to the first antenna unit through a hole in the substrate. The radius of the at least one first slot is one-fourth the wavelength of the central frequency of the antenna structure.

  • Zero Bias Power Detector
    Publication number: 20120062212
    Abstract: A zero bias power detector comprising a zero bias diode and an output boost circuit is provided. The output boost circuit comprises a zero bias transistor. The zero bias diode is not biased but outputs a rectifying signal according to a wireless signal. The zero bias transistor, not biased but coupled to the zero bias diode, is used for enhancing the rectifying signal.
