Publication number: 20090195477Abstract: According to various exemplary embodiments, an antenna assembly generally includes one or more antennas, such as a single multi-frequency antenna, first and second stacked patch antennas, etc. The antenna assembly may be operable for receiving signals having different frequencies (e.g., a frequency associated with a satellite digital audio radio service (SDARS), a frequency associated with a global positioning system (GPS), etc.). The antenna assembly may generally include at least one antenna (e.g., a single multi-frequency antenna, first and second stacked patch antennas, etc.) having at least one feed point and tuned to at least one of a first frequency and a second frequency that is different than the first frequency. A low noise amplifier may be in communication with the at least one feed point for amplifying signals having the first frequency and signals having the second received from a signal output. A single communication link may be used for communicating an output signal of the antenna assembly.Type: ApplicationFiled: April 17, 2009Publication date: August 6, 2009Applicant: Laird Technologies, Inc.Inventors: Cheikh Thiam, Andreas D.

Patent number: 6359593Abstract: A coupling mechanism for (non-radiative) coupling through a dielectric medium, such as the glass of an automobile window, a radiofrequency (RF) antenna signal. The coupling mechanism includes a coaxial conductor for providing the RF antenna signal to a slotline structure (consisting of a layer of metal, deposited on one side of a dielectric substrate such as a circuit board, in which a slot is formed to a depth reaching to the dielectric substrate) mounted typically by an adhesive on one side of the dielectric medium/window glass. On the other side of the dielectric medium/window glass, the coupling mechanism uses either a second slotline structure or a microstrip positioned so as to provide optimal coupling across the dielectric medium/window glass.Type: GrantFiled: August 15, 2000Date of Patent: March 19, 2002Assignee: RecepTec LLCInventors: Ronald A.

Patent number: 6346917Abstract: A method for installing an antenna system having an antenna located exterior to a vehicle. The antenna system has at least one electrically conductive wire to be extended into interior of the vehicle for providing electrical connection to a receiver located in the interior. When the vehicle includes at least one window pane surrounded at least partially by a flexible seal adjacent a weather shield to a portal, the method comprises the steps of positioning the conductive wire in the flexible seal; leading the conductive wire from the flexible seal towards the weather shield; and leading the conductive wire to the receiver through the weather shield.Type: GrantFiled: November 9, 2000Date of Patent: February 12, 2002Assignee: RecepTec LLCInventors: Andreas D.
