Moreover, three resonators optimized by MOEA/D-DE are added to achieve sharp roll-off notched band or three notched bands. For demonstration, the first design is band-notched UWB MIMO antennas with sharp selectivity. Both simulation and measurement show that isolation higher than 22dB and a second-order notched band of 5.15-5.85GHz are achieved in the UWB band.

The surface metal occupancy of the structure is only 6.6%, therefor, a high transparency of more than 90% can be realized theoretically. Simulation results show that shielding effectiveness above 45dB can be achieved throughout the band of 5-30GHz. Additionally, the proposed structure is insensitive to the polarization and the incidence angle of the illumination due to its small unit size.

The radiation sheet is fixed to the PCB board by plastic screws and the PCB board is fixed to the metal cover by metal screws.

The transition of chip to package is firstly investigated, and then the one of chip-package-board and chip-package-board-waveguide. Low loss and wideband impedance matching are realized by carefully designing the redistribution layer in eWLB package and transmission line (TL) on PCB.
