An Emperical Study of the Relative Phase Center Variation of a Ceramic Patch Antenna Mounted on a Vehicle in Multiple Locations
Ran Liu and Daniel N. Aloi, Oakland University
Real Time Kinematic (RTK) is a technology that could be used in future navigation system, such as GPS, Glonass or BeiDou. This technology features high accuracy positioning via processing of satellite carrier phase observables. Due to size and cost constraints, this kind of technology is not prevalent in the automotive sector. However, the push for vehicle autonomy will require RTK positioning solutions. In this paper, a real mass production low-cost small size ceramic patch antenna will be presented from the CST simulation design to real-world production. This patch is studied on a ground plane in a chamber and on a vehicle in several location at an automotive antenna range to document the relative phase center variation for this antenna solution.
