This paper presents millimeter-wave and terahertz double bow-tie slot antennas on a synthesized elliptical silicon lens. Two different antennas are designed to cover 0.1-0.3 and 0.2-0.6 THz, respectively. The double bow-tie slot antenna results in a wide impedance bandwidth and 78-97% Gaussian coupling efficiency over a 3: 1 frequency range. A wideband coplanar-waveguide low-pass filter is designed using slow-wave techniques, and the measured filter response shows an S-21 < -25 dB over a 3: 1 frequency range. Absolute gainmeasurements done at 100-300 GHz and 200-600GHzconfirm the wideband operation of this design. The double bow-tie slot antenna is intended to fill the gap between standard double-slot antennas and log periodic and sinuous antennas, with applications areas in radio astronomy and imaging systems.
