Patent ID: 6950062

Claim:
A phased array antenna having a plurality of phase shifter devices for phase shifting and beam steering a radiated beam of the phased array antenna, said plurality of phase shifter devices interconnected with an interconnect structure comprising a plurality of substrate slats forming walls of the phased array antenna, each of said substrate slats comprising: a metal substrate for supporting the substrate slat; a first dielectric layer applied to the metal substrate in selected areas; metal bias/control circuitry applied to the selected areas on the first dielectric layer; a second dielectric layer applied over the bias/control circuitry; a shielding metal layer applied over the second dielectric layer; circuit terminations connected to the metal bias/control circuitry for control signals and bias voltages and to the shielding metal layer for a ground connection; a respective one of said plurality of phase shifter devices attached to a corresponding one of said plurality of substrate slats and connected to the circuit terminations; and additional circuit terminations connected to the respective metal bias/control circuitry and the shielding metal layer for receiving corresponding supply voltages and phase shifter control signals.
