  • Publication number: 20190165836
    Abstract: An electronic device may include a peripheral conductive wall. A gap in the wall may divide the wall into first and second segments. The device may include a first antenna having a first resonating element arm formed from the first segment and a second antenna having a second resonating element arm formed from the second segment. A non-near-field communications transceiver may perform multiple-input and multiple-output (MIMO) operations using the first and second antennas. The gap may provide satisfactory isolation between the first and second antennas while the first and second antennas perform MIMO operations. Near-field communications circuitry may convey near-field communications signals over a conductive loop path that includes portions of the first and second segments and the antenna ground. The volume of the conductive loop path may extend across substantially all of a width of the electronic device.

  • Patent number: 9206339
    Abstract: A method of preparing a polyester/polyolefin hot-melt adhesive for use in a solar cell bus bar is disclosed, in which 2,6-naphthalenedicarboxylic acid and ethylene glycol are first sequentially subjected in a predetermined ratio to esterification and polycondensation in the presence of a certain amount of a titanium-based catalyst to result in a polyethylene naphthalate (PNT) with a weight-average molecular weight of 16,000˜20,000. The PNT is then melt-blended with a low-density polyethylene (LDPE) in the presence of a compatibilizer to produce the hot-melt adhesive that can be shaped into films having a high light transmittance, good mechanical properties, high heat and yellowing resistance and thus particularly suitable for use in solar cell bus bars.
