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.
