Publication number: 20130307728Abstract: A mobile radio antenna comprises a multi beam forming device which comprises a drivable drive element having a drive shaft and at least two output shafts. Each output shaft is substantially parallel to the drive shaft. At least one output gear is rotationally fixed to the output shaft. At least two phase shifters are each operatively connected to a respective output shaft via a respective drive device. A changeover device enables the drive element to be operatively connected selectively to at least one of the output gears.Type: ApplicationFiled: December 1, 2011Publication date: November 21, 2013Applicant: KATHREIN-WERKE AGInventors: Stefan Berger, Ralf Häntsch

Publication number: 20100182213Abstract: An improved antenna arrangement includes a reflector arrangement comprising a printed circuit board with an electrically conductive ground plane. The reflector arrangement also has a reflector frame with a coupling surface. The coupling surface is capacitively coupled to the ground plane. The coupling surface has a recess via which the ground plane, which is located underneath it, and/or the printed circuit board or an isolating intermediate layer which is provided above the ground plane or an isolating intermediate layer which is provided above the printed circuit board is exposed. The at least one antenna element arrangement is positioned and/or held on the printed circuit board in the area of the recess.Type: ApplicationFiled: July 26, 2007Publication date: July 22, 2010Applicant: Kathrein-Werke AGInventors: Johann Obermaier, Matthias Riedel, Stephen John Saddington

Patent number: 6333720Abstract: A dual-polarized multiband antenna includes first and second radiating element modules having first and second dipole elements. First dipole elements are positioned at right angles to one another to transmit and/or receive radiation in the first frequency band range with two linear orthogonal polarizations. The dipole elements form a dipole square. The second radiating element module transmits or receives radiation in a second frequency band range higher than the first frequency band range. The second module has dipole elements orthogonally related to one another and aligned parallel or at right angles to the first dipoled elements. The second dipoles are arranged in a cruciform.Type: GrantFiled: October 20, 2000Date of Patent: December 25, 2001Assignee: Kathrein-Werke AGInventors: Maximilian Göttl, Roland Gabriel, Georg Klinger
