Abstract EN
Fabrication of a high resistivity silicon based microstrip Rotman lens using a lift-off process has been presented.
The lens features 3 beam ports, 5 array ports, 16 dummy ports, and beam steering angles of ±10 degrees.
The lens was fabricated on a 200 μ m thick high resistivity silicon wafer and has a footprint area of 19.7 mm × 15.6 mm.
The lens was tested as an integral part of a 77 GHz radar where a tunable X band source along with an 8 times multiplier was used as the RF source and the resulting millimeter wave signal centered at 77 GHz was radiated through a lens-antenna combination.
A horn antenna with a downconverter harmonic mixer was used to receive the radiated signal and display the received signal in an Advantest R3271A spectrum analyzer.
The superimposed transmit and receive signal in the spectrum analyzer showed the proper radar operation confirming the Rotman lens design.
