Abstract : —This paper presents the modeling, design and demonstration of two circularly-polarized Transmit-Arrays TA operating in the 60-GHz band and generating a broadside beam and a 30°-tilted beam respectively. These arrays have a fairly simple structure with only three metal layers and are fabricated with a standard printed-circuit board technology. The simulated results show the performances of the unit-cells as well as the whole arrays, and detail their power budget. The experimental results in V-band are in very good agreement with the simulations and demonstrate very satisfactory characteristics. Power efficiencies up to 53.7% are reached with a 1-dB gain-bandwidth up to 9.1%, and low cross-polarization level.

Keywords : 60-GHz band transmit-array unit-cell —Discrete lens millimeter-wave antennas
