Abstract
There is described an integrated antenna for radiating an electromagnetic beam at a wavelength λ, for example, in a range of millimeter and submillimeter waves. The antenna is integrated in a dielectric die having specific dimensions, and is configured as a dense array comprising two or more radiating elements (transmitters). The proposed array is denser than a conventional 1D or 2D array, would such a conventional array be arranged on the same dielectric die with a spacing λ/2 between its neighbouring radiating elements.
