  • Patent number: 11973260
    Abstract: A light-transmitting antenna includes a substrate, a first and a second conductive pattern. The first and the second conductive pattern is disposed on a first and a second surface of the substrate respectively. The first conductive pattern includes a first feeder unit, a first and a second radiation unit, a first and a second coupling unit and a first parasitic unit. The first feeder unit is connected to the second radiation unit. The first and the second radiation unit are located between the first and the second coupling unit. One side and the other side of the first parasitic unit is connected to the second coupling unit and adjacent to the first coupling unit respectively. The second conductive pattern includes a second feeder unit, a third coupling unit, a second parasitic unit, and a fourth coupling unit.

  • Publication number: 20240120656
    Abstract: A light-transmitting antenna includes a substrate, a first conductive pattern, and a second conductive pattern. The first conductive pattern has a first feeder unit, a first radiation unit, a second radiation unit, and a first connection unit. The first feeder unit and the first connection unit are connected to two sides of the first radiation unit. The first connection unit connects the first radiation unit and the second radiation unit. The second conductive pattern has a second feeder unit, a third radiation unit, a fourth radiation unit, and a second connection unit. The second feeder unit and the second connection unit are connected to two sides of the third radiation unit. The second connection unit connects the third radiation unit and the fourth radiation unit. An orthogonal projection of the second feeder unit on a first surface of the substrate at least partially overlaps the first feeder unit.

  • Patent number: 8284360
    Abstract: A liquid crystal display (LCD) panel and a fabricating method thereof are described. First, a first substrate and a second substrate are provided. A liquid crystal monomer layer is then formed on the surface of at least one of the first and second substrates. Next, a curing step is performed to the liquid crystal monomer layer to induce a polymerization reaction, so as to form a liquid crystal polymer layer. Thereafter, the first and second substrates are assembled and a liquid crystal layer is filled between the first and second substrates.
