摘要：
A double folded slot antenna (DFS) has been designed, fabricated, and tested at 90-100 GHz. The antenna shows a very wideband impedance around 20 Ohm from 85 to 110 GHz, The low impedance is compatible with superconductor-insulator superconductor (SIS) junctions, Schottky diodes or high electron mobility transistor (HEMT) amplifiers, which require a low impedance at millimeter-wave frequencies. The antenna is placed on a dielectric lens to synthesize a semi-infinite substrate and realize high-directivity patterns. The measured radiation patterns agree very well with theoretical calculations and demonstrate symmetric main beams and sidelobe levels below -15 dB over a 10% bandwidth. The double folded-slot antenna is an attractive candidate for low-cost wide-band millimeter-wave monolithic microwave integrated circuits (MMIC) front-ends.
