Peripherally-Excited Antenna Arrays: A Practical Realization

The introduction of emerging technologies such as autonomous vehicles, broadband satellite Internet and 5G/6G cellular communication has motivated countless research efforts in millimeter-wave phased arrays, radar systems, and MIMO antennas. The biggest hurdle against the large scale deployment of these technologies is the cost of design, development and manufacturing of the complex antennas required, and overcoming this hurdle will cause an unprecedented impact on our everyday lives. The concept of Peripherally-Excited (PEX) Antenna Arrays is an attractive candidate to satisfy some of the requirements of the aforementioned technologies, at a reduced active component, manufacturing and deployment cost. In this paper, a practical realization of the PEX antenna array is presented for the first time, with experimental verification.
