  • Patent number: 11539140
    Abstract: A reconfigurable antenna, includes an emissive region, including at least one radiating source designed to emit electromagnetic waves; and an electromagnetic lens, including a set of phase-shifting cells, including switches configured to introduce a phase shift to the electromagnetic waves, and bias lines to bias the switches. The antenna further includes an electromagnetic coupling region, arranged between the emissive region and the electromagnetic lens in order to generate electromagnetic coupling between the electromagnetic waves and the set of phase-shifting cells, wherein the electromagnetic coupling region comprises a set of electrically conductive elements, arranged to form a contour of a resonant cavity guiding the electromagnetic waves towards the electromagnetic lens, the set of electrically conductive elements comprising first tracks electrically connected to the bias lines.

  • Patent number: 8917210
    Abstract: A radio frequency integrated circuit (RFIC) chip package is provided having an RFIC chip and an integrated antenna structure. The integrated antenna structure includes an on-chip antenna having one or more radiator elements formed as part of a back-end-of-line structure of the RFIC chip. The antenna structure further includes a superstrate structure disposed on the back-end-of-line structure of the RFIC chip. The superstrate structure includes at least one substrate layer and a focusing metal element. The focusing metal element has a structure that is complementary to the on-chip radiator elements and which is configured to focus electromagnetic radiation to and from the planar antenna structure. The superstrate structure improves the performance (e.g., antenna gain and bandwidth) of the on-chip antennas for millimeter-wave applications.
