Systems for shielding bent signal lines provide ways to couple different antenna arrays for radio frequency (RF) integrated circuits (ICs) (RFICs) associated therewith where the antenna arrays are oriented in different directions. Because the antenna arrays are oriented in different directions, the antenna structures containing the antennas may be arranged in different planes, and signal lines extending therebetween may include a bend. To prevent electromagnetic interference (EMI) or electromagnetic crosstalk (EMC) from negatively impacting signals on the signal lines, the signal lines may be shielded. The shields may further include vias connecting the mesh ground planes and positioned exteriorly of the signal lines. The density of the vias may be varied to provide a desired rigidity in planes containing the antenna arrays while providing a desired flexibility at a desired bending location in the signal lines to help bending process accuracy.

Systems for shielding bent signal lines

A transmission line network is provided that includes a slow-wave transmission line to couple a first terminal to a first antenna. The transmission line network also includes a conventional transmission line to couple a second terminal to a second antenna.

Slow-wave RF transmission network

Exemplary embodiments of the present disclosure are related to inductor shielding. A device may include an inductor and a plurality of conductive strips extending across the inductor. At least a first conductive strip of the plurality of conductive strips is physically isolated from at least a second conductive strip of the plurality of conductive strips in a region of overlay of the first and second conductive strips.
