  • Patent number: 11515648
    Abstract: A dipole antenna is disclosed, which is formed on an electrical circuit substrate having a ground plane and comprises a first antenna group, a second antenna group and a feeding microstrip line, wherein the first antenna group and the second antenna group have the length of a quarter wavelength on the substrate, two feeding points are formed by the intersections of the individual vertical radiating metallic line and the radiating metallic line on two sides, and the feeding microstrip line is connected between the two vertical radiating metallic lines thereby enhancing the radiation signals.
    Type: Grant

  • Patent number: 6653635
    Abstract: A detector with a wide detecting range having a module of electrical circuit boards including an infrared radiation detector element; a stacked-up multifaceted arc lens assembly installed in front of the detector element which is located at the focus of the arc lens assembly to receive the focused infrared rays; and a single deflector plate conjoined to the detector element and mounted on the electrical circuit board, the signal deflector plate having symmetrically constructed reflecting units. Each reflecting unit is composed of a least two reflection planes. The invention is capable of covering detection blind zone exceeding 60 degrees both in right and left directions of the central axis of the detector element, thereby achieving a wide detecting range of over 200 degrees. A method of extending the detecting range is also taught.
