  • High performance dual-patch antenna with fast impedance matching holes
    Patent number: 6977613
    Abstract: A high gain and omni-directive dual-patch antenna (1) for wireless communication under IEEE 802.11b/g standard includes a top and a bottom radiating patches (10) and (20) which have the same dimension, each of which in effect being a ground portion of the other, an air parch dielectric substrate between the two radiating patches, a feeding cable (30) inserted between the two radiating patches, and a support potion (40). A plurality of matching holes (202) is defined in both radiating patches and is provided for fast impedance match tuning and heat dissipation.

  • Optical fiber connector assembly having fiber saver
    Patent number: 6733185
    Abstract: An optical fiber connector assembly (2) includes am optical isolator (10), an optical connector (17) and a fiber saver (11). The optical isolator is received in an isolator tube (19). The fiber saver comprises a helical block (15), a helical block tube (12), two cone members (13, 14) and an extender (18). Optical fiber (102) is wrapped around the helical block, and the helical block is received in the helical block tube-. The two cone members are mounted at the two ends of the helical block tube to prevent movement of the helical block within the helical block tube. The extender receives the helical block tube therein and connects to the isolator tube and to an a adaptor (16). The adaptor couples to the optical connector.
