CHIP-SCALE GYROMETRIC APPARATUS

A chip-scale gyrometric apparatus is disclosed. In embodiments, the chip-scale gyrometric apparatus includes a dielectric substrate (102) and an antenna element (302) attached thereto for receiving an inbound signal having an initial phase. The apparatus includes a splitter (304) for splitting the inbound signal into two equivalent signals, and two coils (106, 108) connected to the splitter. The first coil carries one of the split signals in a clockwise (CW) path relative to a rotational axis, while the second coil carries the other split signal in a counterclockwise (CCW) path relative to the same axis. An integrated circuit (IC) (104) on the substrate and connected to the first and second coils measures a phase shift between the first and second signals (e.g., deviation from the initial phase) based on their respective CW and CCW paths and determines, based on the measured phase shift, a degree of rotation relative to the common rotational axis.
