“…The shape of the main lobe appears to be more frequency dependent in the H-plane than in the E-plane, a behavior also exhibited by our 1.5 GHz horn [9]. The first section alone has a HPBW of 20" in the H-plane and 23" in the E-plane at a frequency of 2.0 GHz; the response at angles greater than 20" is typically 10 dB higher than that of the full antenna in the H-plane and 15 dB higher in the E-plane.…”

“…To further reduce the electric field at the aperture along the E-plane walls and thereby reduce the sidelobes, we mount choke slots at the mouth of the extension the L-band antenna described by Witebsky et al [9] confirm that the response at 150" < 0 < 180" is similar to the response at 90" < 0 < 150" for this type of antenna.…”

A large rectangular horn antenna with a center frequency of 2.0 GHz, corrugated on the E-plane walls, made out of aluminum sheet, has been designed, constructed, and tested. A new technique has been developed to solder thin aluminum strips onto the back plane to form the corrugations. The radiation beam pattern shows half-power beamwidths of 12" and 14" in the H-and E-planes, respectively, and sidelobe response below -40 dB at angles greater than 50" from the horn axis. The measured return loss is greater than 20 dB (VSWR < 1.22) between 1.7 and 2.3 GHz; insertion loss is less than 0.15 dB.

“…They have single corrugated-horn antennas for low sidelobes and were alternately pointed at the zenith, cold load, and an ambient temperature load. The 21-cm corrugated-horn antenna described elsewhere (Witebsky et al 1987) is a large (2 m long by 1.5 m wide) rectangular horn with corrugations in the E-plane walls only. It is separable with only a smaller section viewing the cold load and ambient temperature calibrator.…”

We have measured the temperature of the cosmic microwave background radiation at wavelengths of 0.33, 3.0, 8.2 and 21.3 cm. These measurements represent a continuation of the work reported by Smoot e f al. (1985). The new results have a weighted average of 2.70 & 0.05 K and are consistent with past measurements. They limit the possible distortion of the cosmic microwave background radiation spectrum to less than 6%. The results of all measurements to date are consistent with a Planckian spectrum with temperature 2.74 f 0.02 K spanning a wavelength range of 0.1 to 21 cm.

“…The horn antenna is considered to have a structure equivalent to that of a conventional corrugated horn antenna like the LTCC waveguide does. In the common design, the slot depths of corrugated horn antennas are gradually tapered from to starting at the horn throat to smoothly convert into [20]. However, the design rules for our SIW horn antennas don't follow the same principles as for conventional corrugated horns because of fabrication limitations concerning the slot depth as described above.…”

This paper presents 300-GHz step-profiled corrugated horn antennas, aiming at their integration in low-temperature co-fired ceramic (LTCC) packages. Using substrate integrated waveguide technology, the cavity inside the multi-layer LTCC substrate and a surrounding via fence are used to form a feeding hollow waveguide and horn structure. Owing to the vertical configuration, we were able to design the corrugations and stepped profile of horn antennas to approximate smooth metallic surface. To verify the design experimentally, the LTCC waveguides and horn antennas were fabricated with an LTCC multi-layer process. The LTCC waveguide exhibits insertion loss of 0.6 dB/mm, and the LTCC horn antenna exhibits 18-dBi peak gain and 100-GHz bandwidth with more than 10-dB return loss. The size of the horn antenna is only , which makes it easy to integrate it in LTCC transceiver modules.Index Terms-Dielectric substrates, horn antennas, low-temperature co-fired ceramics (LTCC), terahertz (THz).
