Abstract :
Gain and field pattern measurements at 230 GHz are reported for strip dipole antennas on finite-thickness substrates without ground planes. Four substrate thicknesses are investigated ranging from 0.25 lambda to 1.53 lambda ( lambda =wavelength in substrate material). Measured results are in good agreement with theoretical predictions. A unique detector/low-pass filter design, composed of a bolometer and an interdigitated capacitor, is used to eliminate the distortion of the measured field patterns caused by the reception of the leads connecting the antenna with the monitoring instrumentation.<>
