A flower-shape bio-inspired aperture-coupled antenna array for on-chip application, generated by Gielis formula, operating in industrial, scientific and medical (ISM) band at 60 GHz (57 GHZ to 64 GHz) is presented in this paper. The antenna proposed is composed of a transmission feed line followed by an aperture and patch element built in aluminum, with 2 micrometers of thickness, lying on two layers of silicon with 200 micrometers of thickness each. Dimensions of the antennas were calculated according to the effective wavelength for the resonance frequency at 60 GHz. Simulations were performed in the commercial software ANSYS® Electronics Desktop. The use of the bio-inspired flower-shape promotes more compact structures with greater perimeter, rearranging these shapes into an antenna array provided a gain and a bandwidth increase in the design, 3.11dBi and 2.86GHz, respectively, which resulted in a maximum gain of 8.82 dBi and a total bandwidth of 5.88 GHz.

Abstract This article presents a 60 GHz coplanar fed slotted antenna based on substrate integrated waveguide (SIW) technology for beam-tilting applications. The longitudinal passive slots are fed via associated SIW holes adjacent to the coplanar feed while the main excitation is provided from the microstrip-to-SIW transition. The antenna array achieves an impedance bandwidth of 57–64 GHz with gains reaching to 12 dBi. The passive SIW slots are excited with various orientations of coplanar feeds and associated holes covering an angular beam-tilting from −56° to +56° with an offset of 10° at the central frequency. The novelty of this work is; beam-tilting is achieved without the use of any active/passive phase shifters which improves the design in terms of losses and provide a much simpler alternative compared to the complex geometries available in the literature at the 60 GHz band.
