60 GHz meta-material wideband antenna for FPGA Giga bit data transmission

A 60GHz ultra thin folded dipole antenna on a meta-material structured surface cavity for 3D FPGA high data transmission was proposed. In order to increase the radiation efficiency, meta-material resonant cavity was constructed to act as a reflector. Full wave electromagnetic simulation results reveal that a 4.6 dB gain and 7 GHz bandwidth were obtained at the center frequency of 60 GHz for the novel antenna. The antenna has only 10 mm thick, which is 98% reduction in substrate thickness in comparison with conventional conducting metal cavity antenna having the same gain and bandwidth. The significance of this work is that such low profile antenna can be integrated with standard silicon CMOS technology to make loss cost wireless data transmission possible between FPGA layers or chips.
