The patent application (Publication Number: US20240030621A1) describes an active electronically steerable antenna system that includes a planar or quasi-planar radiating array for transmitting and receiving radiofrequency or microwave signals. The system comprises a plurality of three-dimensional U-shaped modules, each connected to a respective planar radiating subarray of N radiating elements arranged in two rows or columns. Each U-shaped module includes base and side walls forming a three-dimensional structure, with transmit and receive electronics distributed on these walls to implement N transmit and receive modules. The electronics on the base wall are responsible for beam steering functions, signal phase-shifting, and amplification.

Furthermore, the system includes control electronics on the base wall to manage switching, signal splitting, and combination functions. Each U-shaped module also features integrated circuits or discrete electronic components for power amplification, low noise amplification, and switching or circulator functions. The structure of each module is enclosed in a metallic structure for mechanical support and air-cooling, with air passages for efficient cooling. The modules can be arranged side by side in different directions and sizes, with means to generate airflow for cooling through the air passages. Overall, the system provides a versatile and efficient solution for electronically steering antennas for optimal signal transmission and reception.
