Radiation properties of two-element active patch arrays: comparison between calculated and measured results
Mutually coupled active oscillating patches integrated in an array offer beam scanning capabilities. In this paper two-element active patch arrays have been investigated. The radiation patterns have been calculated by using the cavity model, simple Green's function model and a rigorous commercial electromagnetic simulator. Two modified active rectangular patches with a Gunn diode were integrated in arrays in E and H plane. The calculated and measured results for these two active arrays have been compared. Beam scanning capabilities have been demonstrated for both arrays. All three models predicted reasonably well the radiation patterns in the whole steering range. A thin dielectric slab was placed in front of the H plane array to achieve stable operation. The influence of the dielectric slab position on even and odd array operating modes has been demonstrated.
