As 5G, and especially 6G, push into ever-higher frequencies, phase noise presents an increasing problem.

US11637379B2 Decoupled inner slot antenna
In the design of phased array antennas, as well as simple use of compact antennas, there is a strong interest to locate higher frequency antennas closer in spacing, and/or on the same surface, as the larger frequency antennas. What is needed is an array antenna technology, which can be conformal, and can interleave elements, as the frequency increases, to reduce array grating lobes. The desired solution would have much fewer required RF antenna ports, than the Tightly Coupled Dipole Antenna solutions. The optimal solution would also enable Dual or Diverse Polarization. This innovation embeds a wideband Slot Antenna, within the physical area of a larger electric dipole Antenna or Cross Dipole Antenna, with a De-Coupling gap around the Slot Ground Plane (or conductor) and isolates the Wideband Slot Antenna (the inner antenna) from the Dipole or Monopole antenna leg(s) (the Outer Antenna). Both (Inner and Outer) antennas have independent feeds and independent transmission line(s). Two key innovations are the use of a De-Coupling gap, and the use of the patent pending innovation “Compact Single Pole Wideband Slot Antenna Design with Inverted Co-Planar Waveguide Feed”. Both the Inner Slot Antenna and its CPW feed are independent and isolated from the Outer Antenna and its feed and transmission line. This structure, which could have a multiplicity of inner Slot Antennas with numerous RF ports, is very different from the slot or parasitic inner structure within a single port antenna system.
