Abstract
A phase shifting system, a chip, and a radar sensor are provided. A respective transmission line phase-shifting unit is configured to receive at least one phase shifting control signal and to shift a phase of a RF signal by a first phase or a second phase. Each transmission line phase-shifting unit includes a first group of transmission lines and a second group of transmission lines. At least some transmission lines in the first group of transmission lines of each transmission line phase-shifting unit are physically isolated from at least some transmission lines in the first group of transmission lines of an adjacent transmission line phase-shifting unit and transmission lines of the second group of transmission lines of each transmission line phase-shifting unit are coupled to respective transmission lines of the second group of transmission lines of an adjacent transmission line phase-shifting unit.
