Claim 14:
15. A method of manufacturing an integrated antenna for radiating an electromagnetic beam at a wavelength λ belonging to a range of millimeter and submillimeter waves, the method comprising:
integrating an array of two or more radiating elements in a dielectric die having specific dimensions such that the die exhibits the dielectric resonance at the wavelength λ in a direction of the electromagnetic beam emitted from the die perpendicularly to a die radiating surface,
ensuring that each radiating element includes an active integrated circuit for providing radiating power to the radiating element such that each of the two or more radiating elements exhibits the electrical resonance,
while arranging the array so that at least some of the radiating elements neighbouring in the array are placed at a spacing less than λ/4 from one another, and further comprising preliminary steps of:
(1). Selecting dimensions of said dielectric die, such that the die is capable of exhibiting dielectric resonance in a direction of a directable electromagnetic beam emitted from the die perpendicularly to a working (radiating) surface, or determining dielectric resonance for the die having given dimensions;
(2). Selecting the radiating elements, theoretically capable of providing desired Effective Isotopic Radiating Power (EIRP) and Gain in the array;
(3). Determining electrical resonance of the radiating elements;
(4). Adjusting electric parameters of the radiating elements in the array to dimensions of the die so that frequency of dielectric resonance Fdr corresponds to the wavelength λ and becomes substantially a whole harmonic of frequency of electrical resonance Fer,
(5). Selecting a spacing between the neighbouring radiating elements in a one dimension, two dimension, or three dimension array, where the spacing is less than λ/2 from one another;
(6). Selecting a maximal number and a suitable arrangement of the radiating elements in the array within the die having the selected or Given dimensions, at which maximal number the Gain remains substantially constant and maximal, and the EIRP is maximal; and
(7). Bringing the dielectric resonance of the die into correspondence with the electrical resonance of the radiating elements.
