US 2026/0188894 A1 · SYSTEMS AND METHODS FOR A TELEMATICS CONTROL UNIT

Abstract

Embodiments are disclosed for an example telematics system for a vehicle. The telematics system includes a reconfigurable antenna including an antenna portion, a coupling portion, a radiation switch, and a frequency switch. The telematics system further includes a plurality of antennas, and a processor with instructions stored in non-volatile memory to link one antenna of the plurality of antennas to the satellite based on a predicted overlap between a stored radiation pattern of the one antenna and a calculated azimuth and elevation angle of the satellite.

Dependent claims

A reconfigurable antenna of a telematics unit, comprising:

an antenna portion physically coupled to a base;
a coupling portion physically coupled to the base;
a radiation switch electrically coupled to the coupling portion and configured to switch between electrically coupling to a first short ground and electrically coupling to a first open ground;
and
a frequency switch electrically coupled to the antenna portion and configured to switch between electrically coupling to a second short ground and electrically coupling to a second open ground.
