As the demand for high-speed wireless communication grows, millimeter-wave frequencies, such as the 27 GHz band, have become increasingly important for 5G and beyond. However, operating at these frequencies poses technical challenges, such as high propagation losses and atmospheric interference. Now, researchers from China have developed an innovative 2-bit phased array antenna that effectively addresses these issues. Its compact, cost-effective design offers a promising and experimentally verified solution for the future of wireless communications.
