This paper introduces a low‐cost, high‐performance mmWave antenna array module at 77 GH z. Conventional waveguide transitions have been replaced by 3D CPW ‐microstrip transitions which are much simpler to realize. They are compatible with low‐cost substrate fabrication processes, allowing easy integration of IC s in 3D multi‐chip modules. An antenna array is designed and implemented using multilayer coupled‐fed patch antenna technology. The proposed 16 × 16 array antenna has a fractional bandwidth of 8.4% (6.5 GH z) and a 23.6‐ dB i realized gain at 77 GH z.
