Claim 15:
16. An improved integrated antenna for radiating an electromagnetic beam at a wavelength λ belonging to a range of millimeter and submillimeter waves,
Wherein (a) the antenna is integrated in a dielectric die having specific dimensions such that the die exhibits a dielectric resonance at the wavelength λ in a direction of a directable electromagnetic beam emitted from the dielectric die perpendicularly to a die radiating surface; and
Wherein (b) the antenna is configured as an array of two or more radiating elements where each of the two or more radiating elements (i) is capable of providing desired Effective Isotopic Radiating Power (EIRP) and Gain in the array and (ii) includes an active integrated circuit for providing radiating power to the radiating element, and
wherein (c) the array of two or more radiating elements exhibits an electrical resonance, and the dielectric resonance of the array may exist simultaneously with a mutual electric resonance of the two or more radiating elements in the array, and
wherein (d) at least some of the radiating elements neighbouring in the array are placed at a spacing between λ/4-λ/5 from one another, and
wherein (e) the antenna is capable of exhibiting both the dielectric resonance and the electric resonance, corresponding to each other; and
wherein (f) that the die and the two or more radiating elements are adjusted to have frequency of dielectric resonance (Fdr) corresponding to the wavelength λ, which is a whole harmonic of frequency of electrical resonance (Ter); and
wherein (g) a maximal number and a suitable arrangement of the radiating elements are added to the array within the die, such that a maximal number the Gain remains substantially constant and maximal, the EIRP is maximal, and the dielectric resonance of the die corresponds to the electrical resonance of the radiating elements.
