Publication number: 20070080862Abstract: A method for operating an antenna assembly (100) produces a desired overall directional dependence. The antenna assembly (100) comprises at least one first partial antenna (R1) and a second partial antenna (R1+R2), which are disposed relative to each other in such a manner that the individual directional dependences of the partial antennas at least partially overlap. The first partial antenna (R1) is associated with a first antenna signal which represents a radio signal for receiving or transmitting via the first partial antenna (R1), and the second partial antenna (R1+R2) is associated with a second antenna signal which represents a radio signal for receiving or transmitting via the second partial antenna.Type: ApplicationFiled: September 28, 2004Publication date: April 12, 2007Inventors: Bernd Biehlman, Heinrich Gotzig, Frank Kuenzler, Uwe Papziner, Udo Haberland

Publication number: 20070080863Abstract: A sensor network (1) as well as a method for monitoring a terrain (6) is specified. The sensor network (1) has a number of fixed-position sensors (3, 3?, 3?), which can be deployed in the terrain (6), and at least one programming module (25), with the fixed-position sensors (3, 3?, 3?) each being equipped with a communication device, with the at least one programming module having a position-finding device and a programming device (25), in which case the position of the sensors (3, 3?, 3?) can be determined by the position-finding device and can in each case be applied to the sensors (3, 3?, 3?) by the programming device (25) via the communication device, and with the sensors (3, 3?, 3?) being designed such that they themselves form a network. The sensor network (1) as well as the method, which is carried out in a manner corresponding to it, for monitoring the terrain (6) require sensors (3, 3?, 3?) of simple design, and are thus associated with a cost advantage.Type: ApplicationFiled: October 3, 2006Publication date: April 12, 2007Applicant: Diehl Stiftung & Co.

Publication number: 20070080864Abstract: A patch antenna in accordance with the present invention comprises a patch optionally surrounded by a top ground plane, a feed line disposed beneath the patch and separated therefrom by a thin substrate, a middle ground plane separated from the feed line by another thin substrate, and a bottom ground plane disposed beneath the middle ground plane and preferably separated therefrom by foam or another lightweight dielectric layer. Conductive vias run between the top ground plane and the middle ground plane as well as from the middle ground plane to the bottom ground plane. The middle ground plane is essentially annular, defining an opening in the middle thereof, such that there is a dielectric cavity beneath the patch and the feed line in the space defined by the bottom ground plane, the middle ground plane and the vias that run between the middle ground plane and the bottom ground plane. This cavity can be filled with low cost, low weight foam, rather than the heavier, more costly conventional substrates.Type: ApplicationFiled: October 11, 2005Publication date: April 12, 2007Applicant: M/A-Com, Inc.Inventor: Eswarappa Channabasappa

Publication number: 20070080866Abstract: An antenna for receiving electromagnetic waves in a desired frequency band, includes a radiating conductor and a ground conductor, a feeder part, a wavelength-shortening section, and a magnetic field applying section. The radiating conductor and a ground conductor resonate at a resonance point frequency. The feeder part is configured to feed the radiating conductor with electricity. The wavelength-shortening section in which a magnetic body having both a dielectric property and a magnetic property is disposed close to the radiating conductor shifts the resonance point frequency into a band lower than the desired frequency band by a wavelength-shortening effect obtained based on the dielectric property and the magnetic property. The magnetic field applying section is configured to apply a magnetic field to the magnetic body so as to reduce a magnetic loss due to the magnetic body.Type: ApplicationFiled: August 29, 2006Publication date: April 12, 2007Inventors: Masatoshi Hayakawa, Kiyotada Yokogi, Yoshimi Takahashi, Kenji Asakura, Shuichi Goto
