Connected slots antenna array feeding a high-gain lens for wide-angle beam-steering applications

Wide Angle Decentered Lens Beam Steering for Infrared Countermeasures Applications

Integrated phased array for wide-angle beam steering.

We demonstrate an on-chip optical phased array fabricated in a CMOS compatible process with continuous, fast (100 kHz), wide-angle (51°) beam-steering suitable for applications such as low-cost LIDAR systems. The device demonstrates the largest (51°) beam-steering and beam-spacing to date while providing the ability to steer continuously over the entire range. Continuous steering is enabled by ...

Design of Controlled RF Switch for Beam Steering Antenna Array

A printed dipole antenna integrated with a duplex RF switch used for mobile base station antenna beam steering is presented. A coplanar waveguide to coplanar strip transition was adopted to feed the printed dipole. A novel RF switch circuit, used to control the RF signal fed to the dipole antenna and placed directly before the dipole, was proposed. Simulated and measured data for the CWP-to-CPS...

Design of a Reconfigurable Reflectarray Unit Cell for Wide Angle Beam-Steering Radar Applications

A reconfigurable aperture-coupled reflectarray element is proposed for the realization of beam steering antennas, suitable for radar applications. Each reflectarray element is coupled to a microstrip line, which is loaded by a single varactor diode acting as a phase shifter element, thus providing a continuously variable reflection phase. A reduced size reflectarray unit cell is properly design...

Antenna Array Designs with Advanced Beam Steering Capabilities

Two new antenna array designs with advanced beam steering capabilities are described. The first is based on an integrated design using Ferroelectric and Continuous Transverse Stub (CTS) technologies, while the other is based on a hybrid smart antenna approach that combines the desired features from both the adaptive and switched beam approaches. The complementary features of these two analog an...
