摘要：
An integrated corner-reflector antenna has been designed, fabricated and measured at millimeter-wave frequencies. The structure consists of a travelling-wave antenna integrated on a 1.2-mu-m dielectric membrane and suspended in a longitudinal cavity etched in a silicon wafer. A new traveling wave antenna design, the modified-bend antenna, with an antenna length of L = 1.2-lambda and spacing d = 0.96-lambda from the apex, results in a wide-band input impedance centered at 140 OMEGA and low cross-polarization levels. Measurements at 180-270 GHz show a well defined pattern with low sidelobe levels and a main-beam efficiency of 93 and 83% at 180 and 222 GHz, respectively. The monolithic approach allows the integration of a matching network and a Schottky-diode or SIS detector at the base of the antenna to yield a low-noise monolithic millimeter-wave receiver.
