Patent number: 6967618Abstract: An antenna of a radio apparatus, the directional pattern of which can be altered controllably. The antenna comprises at least one conductive element, additional from the viewpoint of the basic operation of the antenna, for shaping the directional pattern of the antenna. Such a conductive element (330, 340) is connected to signal ground at a ground point relatively near the feed point (F) of the antenna. The conductive element has a part (331) the length of which is about a quarter of the wavelength at an operating frequency of the antenna, pointing from the ground point (G) in a direction substantially opposite to the feeding direction of the radiating element (320). That part is used to equalize the directional pattern of the antenna in the receiving band. In addition, the conductive element has a second part (332) pointing from the ground point to the feeding direction of the radiating element to set a directional pattern notch at transmitting band frequencies in a desired direction.Type: GrantFiled: April 4, 2003Date of Patent: November 22, 2005Assignee: Filtronic LK OyInventors: Seppo Ojantakanen, Timo Leppäluoto

Patent number: 6965347Abstract: A receiver includes a circuit board and a dielectric antenna. The circuit board has a receiving circuit on a first surface, and a ground pattern on a second surface. The circuit board is disposed close to a rear window of a vehicle so that the ground pattern faces a roof panel. The dielectric antenna extends from an edge of the circuit board toward and along the rear window. As a result, the roof panel capacitively couples with the ground pattern, so that the roof panel becomes imaginary ground. The dielectric antenna functions as a monopole antenna with the imaginary ground. It is not influenced with a metallic material of the vehicle.Type: GrantFiled: August 29, 2003Date of Patent: November 15, 2005Assignees: Nippon Soken, Inc., Denso CorporationInventors: Yuji Sugimoto, Syuichi Kono, Masahito Hirayama, Tomoyuki Miyagawa, Gorou Inoue

Patent number: 6963308Abstract: An internal multiband antenna and a radio device intended particularly for small-sized radio devices. The antenna has a relatively wide surface radiator (330), which is electromagnetically connected to the antenna port of the radio device via a separate feed element (320). At least two useful resonances are generated with the aid of the feed element, and at least one inherent resonance of the radiator is also utilized. The radiator has a hole (350), by which one useful additional resonance is generated. An oscillation is excited in the hole by placing the feed element close to its edge and by suitably choosing the locations of the feed point (F) and the shorting point (S) of the feed element. The frequency of the hole resonance is finely tuned by varying the capacitance between the hole's edge and the ground plane at a suitable place (331). An operating band of the antenna can be widened by means of said additional resonance.Type: GrantFiled: January 7, 2004Date of Patent: November 8, 2005Assignee: Filtronic LK OyInventor: Heikki Korva

Patent number: 6956535Abstract: An antenna for generating radiation includes a primary E-field generating circuit and a secondary E-field generating circuit. The primary E-field generating circuit generates a primary E-field in response to a source RF signal being applied to the antenna. The secondary E-field generating circuit generates a secondary E-Field, disposed apart from the primary E-field, in response to the source RF signal and develops an H-field that is in time phase with the primary E-field. This causes the antenna to develop a radiation resistance as an indication of radiation.Type: GrantFiled: June 30, 2003Date of Patent: October 18, 2005Inventor: Robert T. Hart

Patent number: 6956568Abstract: Umbilics of two surfaces are compared and it is determined from this comparison whether the suspect surface is a copy of the original surface based on the comparison. Comparing umbilics includes determining whether locations of the umbilics of the suspect surface match within a specified margin umbilics of the original surface, and determining whether pattern types of umbilics of the suspect surface match pattern types of corresponding umbilics of the original surface. A “weak” test may be performed, in which corresponding points on the two surfaces are compared, wherein the comparison of umbilics is performed if corresponding points of the two surfaces are located within a specified margin of each other. The points may be gridpoints on wireframes, which in turn may be based on lines of curvature of the surfaces. Comparing umbilics is performed if it is determined that each surface has at least one umbilic.Type: GrantFiled: January 9, 2002Date of Patent: October 18, 2005Assignee: Massachussetts Institute of TechnologyInventors: Takashi Maekawa, Nicholas M.

Patent number: 6937206Abstract: The present invention refers generally to a new family of antenna arrays that are able to operate simultaneously at two different frequency bands, while featuring dual-polarization at both bands. The design is suitable for applications where the two bands are centered at two frequencies f1 and f2 such that the ratio between the larger frequency (f2) to the smaller frequency (f1) is f2/f1<1.5. The dual-band dual-polarization feature is achieved mainly by means of the physical position of the antenna elements within the array. Also, some particular antenna elements are newly disclosed to enhance the antenna performance.Type: GrantFiled: October 15, 2003Date of Patent: August 30, 2005Assignee: Fractus, S.A.Inventors: Carles Puente Baliarda, Jaime Anguera Pros, Carmen Borja Borau
