Wideband linearly polarized transmitarray antenna for 60 GHz backhauling

Abstract : This communication presents the design of a linearly-polarized transmitarray antenna for backhauling applications at V-band (57-66 GHz). The antenna is composed of a planar circular-shape array with 1264 unit-cells printed on a three-metal layer standard PCB, an ad-hoc focal source, and a radome layer. A 3-bit phase resolution has been selected to achieve a gain higher than 31 dBi over the whole unlicensed 60 GHz-band and low side lobe levels. The presence of the radome near the array is taken into account in the unit-cell design. Experimental results are in line with the theoretical ones provided by an in-house CAD tool based on analytical model and electromagnetic simulations. The proposed design presents a measured broadside gain of 32.5 dBi at 61.5 GHz with an aperture efficiency of 42.7% and a wide 1-dB gain bandwidth of 15.4% (57-66.5 GHz).
