  • Patent number: 12191900
    Abstract: A millimeter wave radio frequency (RF) structure uses a substrate including a liquid-crystal polymer material, at least one dual-polarized antenna, a RF transceiver module, and a switching module electrically connected to the at least one dual-polarized antenna and the RF transceiver module, where the switching module includes a first switching element and a second switching element electrically connected to the at least one dual-polarized antenna, and a third switching element electrically connected to the first switching element and the second switching element, to enhance characteristics of a liquid-crystal polymer (LCP) substrate for millimeter waves, and implement high-frequency, high-speed transmission while ensuring high reliability.

  • Patent number: 11967762
    Abstract: An antenna structure includes a substrate, a plurality of reflective plates, a grounding plate, a radiating member, a signal feeding via and a plurality of conductive vias. The substrate has opposite first and second surfaces and comprises liquid crystal polymer. The reflective plates are arrayed on the first surface of the substrate. The grounding plate is disposed on the second surface of the substrate and overlapped with the reflective plates in a normal direction of the substrate. The grounding plate further includes an opening. The radiating member is disposed on the first surface of the substrate and physically separated from the reflective plates. The signal feeding via is coupled with the radiating member and penetrates through the substrate to be exposed in the opening of the grounding plate. The conductive vias penetrate through the substrate and respectively connect the reflective plates and the grounding plate.

  • Patent number: 11862869
    Abstract: An antenna structure includes a substrate, a plurality of reflective plates, a grounding plate, a radiating member and a plurality of conductive vias. The substrate contains liquid crystal polymer and has opposite first and second surfaces. The reflective plates are arranged in an array on the first surface of the substrate. The grounding plate is arranged on the second surface of the substrate and overlaps with the reflective plates in a normal direction of the substrate. The radiating member is on the second surface of the substrate and does not overlap with the reflective plates in the normal direction of the substrate. The radiating member has an open slot which is defined by a first radiating branch and a second radiating branch that generate at least two different operating frequency bands. The conductive vias respectively penetrate the substrate and connect with the reflective plates and the grounding plate.

  • Publication number: 20230299450
    Abstract: A three-dimensional (3D) filter and a fabrication method thereof are provided. The 3D filter includes a circuit board, a first ring-type resonator, a second ring-type resonator and a via structure. The circuit board includes a first circuit layer, a second circuit layer and a third circuit layer. The third circuit layer is located between the first circuit board and the second circuit board. The first ring-type resonator is disposed in the first circuit layer and has a first surrounding area corresponding to a first cut-off frequency band. The second ring-type resonator is disposed in the second circuit layer and has a second surrounding area corresponding to a second cut-off frequency band. The via structure passes through the first circuit layer, the second circuit layer and the third circuit layer, and is electrically connected to the first ring-type resonator and the second ring-type resonator.
