Multidimensional Beam Coverage Millimeter-Wave Phased Antenna Array

This article introduces a millimeter wave patch dipole antenna array. It examines and addresses coupling effects by simultaneously exciting common mode (CM) and differential mode (DM) signals on two dipoles separated by 1/4 λ

. Manipulating the phase difference between two dipole antennas results in four entirely different radiation patterns: omnidirectional, two distinct unidirectional patterns, and a bidirectional radiation pattern. Encompassing a 360° beam coverage, these four radiation patterns serve as a solution for multi-dimensional communication within millimeter wave applications.
