Abstract
Reducing azimuth-elevation correlation in an antenna array structure is provided. Herein, an antenna array structure is configured to include multiple active antenna elements and a single passive antenna element. In an embodiment, the active antenna elements are each coupled to a respective antenna port and the passive antenna element is isolated from all of the antenna ports. In other words, the passive antenna element acts as a dummy antenna element that can absorb electromagnetic energy of a radio frequency (RF) signal but does not provide the received RF signal to any of the antenna ports. The presence of the passive antenna element makes it possible to reduce an azimuth-elevation correlation between each orthogonal pair of active antenna elements in the antenna array structure to thereby improve accuracy of phase-difference-of-arrival (PDoA) measurements and location determination in an azimuth-elevation coordinate system.
