W-Band High-Efficiency Waveguide Slot Array Antenna with Low Sidelobe Levels Based on Silicon Micromachining Technology
文献摘要：
A high-efficiency waveguide slot array antenna with low sidelobe level(SLL)is investigated for W-band applications.The silicon micromachining techno-logy is utilized to realize multilayer antenna architecture by three key steps of selective etching,gold plating and Au-Au bonding.The radiating slot based on this tech-nique becomes thick with a minimum thickness of 0.2 mm and accompanies with the decrease of slot's radiation abil-ity.To overcome this weakness,a stepped radiation cav-ity is loaded on the slot.The characteristic of cavity-loaded slot is investigated to synthesize the low-SLL ar-ray antenna.The unequal hybrid corporate feeding net-work is constructed to achieve sidelobe suppression in the E-plane.A pair of 16×8 low-SLL and high-effciency slot arrays is fashioned and confirmed experimentally.The bandwidth with the radiation effciency higher than 80％is 92.3-96.3 GHz.The SLLs in both E-and H-planes are be-low-19 dB.
