| Summary: | Highly integrated multilayered printed circuit board-based patch antenna arrays are proposed
in this study for 60 GHz wireless communications. Electromagnetic coupling
between two stacked patches is used to achieve the broadband performance.
Different structures of single element antennas, two-element antenna arrays and
four-element antenna arrays are presented. The two compact four-element antenna
arrays show < −10 dB impedance bandwidth of 13 and 14.6% with 12 dBi peak
gain. The arrays have the 3 dB gain bandwidth of 9 and 13%. A single column,
four-element sub-array is used to design 4 × 16 antenna array. This
array delivers 20.8 dBi peak gain with 13% impedance and gain bandwidth.
Furthermore, a two-element series fed array is used to realise a 2 × 16 phased
antenna array. This array is fed through a 16 × channel radio frequency IC to
achieve the beam steering in [inline-formula] range.
