International audience—In this letter, we investigate using a two-element parasitic (loaded) superdirective antenna as a unit-element to achieve a compact 3D array. Four elements of a planar parasitic superdirective antenna are integrated in a compact 2 × 2 array for UHF band. The array final dimensions are 200 × 200 × 70mm 3 (0.58λ × 0.58λ × 0.2λ), and it presents a maximum simulated total directivity of 11.4dBi. The antenna dimensions are significantly smaller than classical commercial arrays achieving the same directivity. The measured results are in a good agreement with the simulated ones
