    摘要: A phase shifter is provided, which includes a first substrate, a second substrate, a liquid crystal layer, a plurality of first ring-shaped electrodes and a plurality of second ring-shaped electrodes. The first substrate and the second substrate are disposed opposite to each other. The liquid crystal layer is disposed between the first substrate and the second substrate. The plurality of first ring-shaped electrodes are disposed sequentially and in interval on a side of the first substrate close to the liquid crystal layer. The plurality of second ring-shaped electrodes are disposed sequentially and in interval on a side of the second substrate close to the liquid crystal layer. A plurality of vertical projections, projected by the plurality of first ring-shaped electrodes to the second substrate, and at least partially overlapped with the plurality of second ring-shaped electrodes, respectively.

    摘要: 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.
