PROJECT TITLE :

Dynamic Polarization Control of Two-Dimensional Integrated Phased Arrays

ABSTRACT:

Simultaneous 2-dimensional (2-D) beam steering and dynamic polarization management (DPC) of the radiated electrical field in 2-D phased arrays ensure polarization matching between the transmitter and receiver antennas in each fixed and mobile wireless systems. Polarization matching is maintained regardless of the polarization, orientation, and site of the receiver antenna in space inside the two-D steering range of the transmitter. This work implements a fully integrated two × 2 DPC phased-array transmitter during a thirty two-nm CMOS silicon-on-insulator method, radiating at 122.9 GHz. It achieves a most effective isotropic radiated power of +twelve.three dBm in the broadside direction and enables polarization angle control of the radiated linear and elliptical polarizations across the total range of zero ° to 180 ° with tunable axial ratio right down to one.2 dB to realize circular polarization and the power to steer the radiated beam up to 15 ° in each dimensions.
