Patent number: 9755723Abstract: A method, system, and medium are provided for improving uplink performance of an antenna array configured for downlink beam forming. Beam forming requires an antenna element spacing that results in correlated downlink signals. Uplink reception preferably uses an element spacing such that uplink signals are uncorrelated.

Patent number: 9583836Abstract: An antenna is connected to a first end of a high-frequency transmission line, and a connector is connected to a second end of the high-frequency transmission line. A characteristic impedance of a microstrip line is higher than characteristic impedances of first and second strip lines, and a characteristic impedance of a coplanar line is higher than a characteristic impedance of the second strip line.

Patent number: 9007268Abstract: An antenna has an antenna body having a plurality of first antenna elements, which are disposed along a first straight line. A hollow conductor, which extends between the first antenna elements, is disposed in the antenna body. The first antenna elements are developed as openings running between the hollow conductor and a surface of the antenna body. The antenna is designed to radiate a signal in a spatial direction that is a function of a frequency of the signal. The antenna body has an electrically insulating material that is coated with a conductive material.Type: GrantFiled: December 28, 2010Date of Patent: April 14, 2015Assignee: Robert Bosch GmbHInventors: Thomas Focke, Joerg Hilsebecher, Oliver Lange, Reinhard Meschenmoser, Arne Zender, Thomas Schoeberl, Thomas Hansen, Joachim Selinger, Karl Schneider
