| 20080198086 | Planar Antenna With Conductive Studs Extending From The Ground Plane And/Or From At Least One Radiating Element, And Corresponding Production Method - The disclosure relates to a planar antenna comprising at least one radiator element separated from a ground plane by a dielectric. The antenna also comprises an assembly of conductive studs which is connected to and extends from at least one element of a group of elements comprising the ground plane and at least one radiator element in such a way that at least one physical dimension of said at least one radiator element for a determined resonance frequency is reduced. | 08-21-2008 |
| 20090213025 | Ultra-wideband antenna with excellent design flexibility - An ultra-wideband antenna includes a zone, an excitation means, and an adapting means. The zone is defined between first and second shaped surfaces such as to form a radiating element. The first and second shaped surfaces are also rotationally symmetrical in relation to a longitudinal axis of the antenna, and are disposed opposite one another in respect of a plane that is orthogonal to the longitudinal axis and that contains a horizontal axis. The first and second shaped surfaces are configured to control the characteristics of an electromagnetic field in the zone such that the antenna has an essentially-constant gain in the frequency band along an azimuth plane. The excitation means is configured to supply a signal in a localised manner in a central region of the zone. The adapting means is configured to promote a localised coupling between the excitation means and the zone. | 08-27-2009 |
| 20090213562 | System for interconnecting two substrates each comprising at least one transmission line - The present invention relates to an interconnection system of a first substrate ( | 08-27-2009 |
| 20100066622 | MULTI-SECTOR ANTENNA - The present invention relates to a multi-sector antenna comprising N (N>1) planar antennas each constituted of a longitudinal radiation slot etched on a first substrate provided with a ground plane and supplied by an excitation line. The N first substrates are fixed on a second common substrate so that the radiation axis of each antenna is parallel to said second substrate, the N first substrates being interconnected around an axis perpendicular to the second substrate. The invention can be applied to high definition wireless cameras. | 03-18-2010 |
| 20100097120 | Electronic Switching Device for High-Frequency Signals - The invention relates to an electronic switching device for high-frequency signals. The invention is of particular use in the connection between a microwave frequency antenna and an electronic circuit. This circuit comprises one or two access points designed to be connected to the antenna forming a third access point. In the case of a switch between one access point and the antenna (called an SPST switch), it comprises two switching diodes, one, called a serial diode, being connected in series between the access points and the other, called a shunt diode, between one of the access points and an earth of the device. According to the invention, a first transmission line is placed in series with the shunt diode, a second transmission line is placed in series with the serial diode, a third transmission line is placed at the common point of the first transmission line and of the shunt diode, a fourth transmission line is placed at the first access point, and a fifth transmission line is placed at the second access point. For a switch with three access points, two other diodes and four other transmission lines are added in a symmetrical manner relative to those already described. It is possible to obtain adapted lines having lengths much shorter than λ/4, which makes it possible to improve the compactness of the device while increasing its bandwidth. | 04-22-2010 |
