access icon free Directive and high-efficiency slotted waveguide antenna array for V-band made by wire electrical discharge machining

High-efficiency and directive antennas are nowadays required for wireless communications and applications in the 57–66 GHz ISM band. A slotted waveguide antenna array operating at 58.8 GHz and made in aluminium by wire electrical discharge machining and a milling technique is presented. A −10 dB bandwidth of 3.54 GHz is achieved while the antenna exhibits a measured realised gain of 10.7 dBi at a resonance frequency of 58.8 GHz, with a high total efficiency of 95%. By defining the simulation model under CST according to the accuracy of the manufacturing process, simulation and measurement results are in excellent agreement.
