The multiband antenna includes a Printed Circuit Board (PCB), at least one radiation unit, and a feeding unit. The PCB is formed within a radome that protects the antenna. The at least one radiation unit is formed on the PCB to be optimized as a Hilbert type meander line composed of a single pattern, and is configured to generate multiband resonant frequencies. The feeding unit is configured to apply signals to the radiation unit.Type: ApplicationFiled: September 1, 2006Publication date: October 18, 2007Applicant: Motonix Co., Ltd.Inventors: Tae-Kwan Cho, Young-Sup Bang, Jin-Ho Kim

Patent number: 7280079Abstract: An object of the invention is to provide an adaptor device for a car radio capable of improving the receiving state. The adaptor device 20 for a car radio is connected to a vehicle-mounted antenna connection terminal 12 provided in an FM radio receiver 10 installed within a vehicle room, and includes a signal line inserted between the vehicle-mounted antenna connection terminal 12 and a vehicle-mounted antenna 110; and an in-vehicle antenna 22 branching out from the signal line. A radio wave transmitted from an FM transmitter 40 disposed within the vehicle room via an antenna 42 is received by the radio receiver 10 via the in-vehicle antenna 22.Type: GrantFiled: January 4, 2006Date of Patent: October 9, 2007Assignee: Neuro Solution Corp.Inventor: Hiroshi Miyagi

Patent number: 7271773Abstract: In an antenna adapted to be mounted on a vehicle body, a base member supports a base end of the antenna element. A screw member is extended from the base member and adapted to be inserted into a though hole formed in the vehicle body. A wall member is extended from the base member to define a housing space. A circuit board is disposed in the housing space. A casing covers the housing space such that an inner face thereof comes in contact with an outer face of the wall member. A waterproofing member is disposed between the base member and the vehicle body so as to surround an entire periphery of the through hole.Type: GrantFiled: October 19, 2005Date of Patent: September 18, 2007Assignee: Yokowo Co., Ltd.Inventors: Tatsuo Gorai, Sadao Ohno

Publication number: 20070210979Abstract: An exterior vehicle component includes a proximity member disposed along an outer perimeter of an electromagnetic wave transmission member provided at a center of the component which is disposed in front of a radar device. The proximity member includes a chromium-plated portion formed on its front surface which reflects an electromagnetic wave. The proximity member is formed of an acrylate-styrene-acrylonitrile resin or a modified polyphenylene oxide resin having an attenuation coefficient for electromagnetic wave transmission, which is equal to or greater than a predetermined value.Type: ApplicationFiled: February 12, 2007Publication date: September 13, 2007Inventor: Masahito Shingyoji

Patent number: 7268734Abstract: Exemplary embodiments of mountable antenna apparatuses and methods are disclosed. In one exemplary embodiment, a mountable antenna apparatus generally includes a housing member, a bayonet adapter, and an antenna assembly disposed within the housing member. The housing member may include an aerodynamic configuration for reducing drag on and for eliminating or reducing fatigue as well as flutter of the antenna assembly. The aerodynamic configuration may include a feature such as an ogive, an ogivoid, a semi-ogivoid, a hemi-ogivoid, and a quasi-ogivoid.Type: GrantFiled: February 2, 2006Date of Patent: September 11, 2007Assignee: Antenex, Inc.Inventor: Donald M. Cislo

Patent number: 7265725Abstract: A cutout portion through which one end side of a U-shaped portion of the antenna passes is cut deeper than a preset passing position where the U-shaped portion passes through the cutout portion. Further, an open dimension of a through hole through which the other end side of the U-shaped portion passes is substantially twice an outer diameter dimension of the U-shaped portion. When the U-shaped portion is passed through the through hole at the preset passing position, the U-shaped portion passes through the substantial center of the through hole. When error arises in the retention position of the antenna and the fixing position of the base plate, the U-shaped portion is displaced inside the cutout portion and the through hole, and the above error is absorbed.Type: GrantFiled: March 22, 2006Date of Patent: September 4, 2007Assignees: Kabushiki Kaisha Tokai-Rika-Denki-Seisakusho, Toyota Jidosha Kabushiki KaishaInventors: Nana Nakajima, Hiroaki Kojima

Patent number: 7253778Abstract: An antenna is incorporated into the cowl grille of a motor vehicle adjacent the front windshield. The antenna comprises a receiver module or component and wire or cable which extends along the cowl grille generally parallel to the front windshield. The wire or cable can extend outside the cowl grille, and terminates in a connector which can be fed to the passenger compartment of the vehicle for connection to a radio, or the wire or cable can terminate as a molded-in connector as part of the cowl plastic allowing for direct connection from the vehicles wiring harness.Type: GrantFiled: September 7, 2005Date of Patent: August 7, 2007Assignee: ADAC Plastics, Inc.Inventors: Robert L. Bingle, Joseph Meinke
