Compact photonic integrated phase and amplitude controller for phased-array antennas

Feasibility of an extremely compact photonic integrated circuit for controlling phase and amplitude of a 16-element phased-array microwave antenna has been demonstrated experimentally.

Photonic chip for steering a four element phased array antenna

A polarization independent photonic integrated circuit for phase steering of a four element phased array antenna has been fabricated on InP. The chip is extremely small and suitable for packaging.

A Comparison Between the Green's Functions of Connected Slots and Dipoles in the Presence of a Backing Reflector

In this paper the impedances of connected arrays of slots and dipoles are presented. The study is based on the rigorous Greens Functions (GF) of the two structures in infinite array environments. The preliminary investigations indicates that the potentials of the connected slots when scanning are limited, due to the excitation of a leaky wave mode that can propagate between the continuous and the slotted metallic planes. The connected dipoles do not suffer from any such poles.
