MILLIMETER-WAVE ANTENNA ARRAY APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240047854 titled 'MILLIMETER-WAVE ANTENNA ARRAY APPARATUS
Simplified Explanation
The present invention is a millimeter wave RF antenna array apparatus that includes a single-chip MMIC (Monolithic Microwave Integrated Circuit) with active circuit elements. The active circuit elements consist of antenna feed circuitry designed to feed the antenna elements of the array. The apparatus also includes an interposer made of low-loss RF material, such as glass, LTCC (Low-Temperature Co-Fired Ceramic), or PCB (Printed Circuit Board). The interposer contains transmission lines of an RF distribution network and multiple antenna elements of the array. These transmission lines are coupled to the MMIC to provide RF connections for distributing RF signals to and from the antenna feed circuitry. The area of the interposer that contains the transmission lines and antenna elements is located together with the area of the MMIC that contains the antenna feed circuitry.
