Patent number: 8519890Abstract: A planar bi-directional radiation antenna including a substrate, a first reflecting element, an antenna body, a second reflecting element and a third reflecting element is provided. The first reflecting element is concaved inwards to form a first notch in a first surface. The antenna body is located inside the first notch, and is symmetrical to a predetermined direction with the first reflecting element. The second reflecting element is concaved inwards to form a second notch in a second surface. The configuration of the first notch and the second notch is correspondingly disposed along a vertical projection plane with respect to the substrate. The third reflecting element is opposite to the antenna body along the predetermined direction, and covers an opening of the first notch, so that the antenna generates two beams, wherein the two beams have an angle relative to the substrate, so as to achieve a bi-directional radiation effect.Type: GrantFiled: January 18, 2011Date of Patent: August 27, 2013Assignee: HTC CorporationInventors: Huan-Chu Huang, Chien-Ting Chen

Patent number: 8502746Abstract: A planar directional antenna including a substrate, a metal layer, a master antenna, and an auxiliary antenna is provided. The substrate has a first surface and a second surface. The metal layer is disposed on the second surface of the substrate, and an upper edge of the metal layer forms a concave parabolic curve. The master antenna is disposed on the substrate and located within a predetermined range of the focus of the concave parabolic curve. The auxiliary antenna is disposed on the substrate and opposite to the master antenna so that the planar directional antenna generates a beam toward a radiation direction.Type: GrantFiled: November 16, 2009Date of Patent: August 6, 2013Assignee: HTC CorporationInventor: Huan-Chu Huang

Patent number: 8482473Abstract: A planar reconfigurable antenna including a substrate, a metal layer, a master antenna, an auxiliary antenna and a switch set is provided. The substrate has a first surface and a second surface. The metal layer is disposed on the first surface of the substrate and the upper edge of the metal layer is in a convex arc shape. The master antenna is disposed on the substrate and partially overlaps the metal layer on a vertical plane of projection. The auxiliary antenna is disposed on the substrate and is placed opposite to the master antenna. The switch set is also disposed on the substrate and changes a connection relation of a plurality of directional devices in the auxiliary antenna to switch scanning directions of main beams generated from the planar reconfigurable antenna.Type: GrantFiled: August 27, 2009Date of Patent: July 9, 2013Assignee: HTC CorporationInventor: Huan-Chu Huang

Patent number: 8264418Abstract: A planar antenna with an isotropic radiation pattern is provided. The planar antenna includes a substrate, a dipole antenna, a microstrip line set, and a channel selection module. The dipole antenna is disposed on a first surface of the substrate, and the microstrip line set and the channel selection module are disposed on a second surface of the substrate. A first microstrip line and a second microstrip line of the microstrip line set are spirally extended along two opposite rotation trails on a vertical projection plane to form a high-frequency path with the dipole antenna. The planar antenna controls the on/off state of the channel selection module so that a low-frequency path is formed when the dipole antenna is connected to a first line and a second line. A plurality of channels having different operating frequencies is respectively generated within the high-frequency path and the low-frequency path.Type: GrantFiled: November 17, 2009Date of Patent: September 11, 2012Assignee: HTC CorporationInventor: Huan-Chu Huang
