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).

“…The packing cavity has a size which is about twice time larger than that of the DR therefore the resonant frequency and the unloaded Q of the DR would not be seriously affected by the current induced on the metallic surface by the external field of the resonator. The dimension of the rectangular horn antenna is designed by [10]. The surface mount Schottky diodes of SMS7621-079 (Alpha) is used to be mixer M1 and GaAs MESFET T1 is NE76184 (NEC).…”

In this article, a high quality vehicle RF module integrated with a temperature stable dual‐band dielectric resonator oscillator (DRO) oscillating at X‐ and K‐band simultaneously is implemented. The DRO shows the first oscillating frequency at 11.545 GHz and the second oscillating frequency at 23.09 GHz using the fundamental TE01 and enhanced TE02 mode of the dielectric resonator (DR), respectively. The used DR is (Zr, Sn)TiO4 ceramic with a dielectric constant (εr) of 36, a quality factor (Q×f) of 60,000 and a temperature coefficient of resonant frequency (τf) of ± 1 ppm/°C. The design procedure is clearly described in this article. The propagation mode behaviors and equivalent circuits of the DRO are used to predict the circuit performances of the RF module. For practical testing, the RF module combining with a horn antenna, the DRO and a surface‐mounted mixer is fabricated and measured. The results are close matched with the circuit simulation. © 2008 Wiley Periodicals, Inc.

“…The scattering coefficients for the complete horn are obtained by cascading the matrices for each junction, which give the aperture field. Far‐field radiation patterns can then be obtained by techniques like Huygen's principle or the field equivalence principle (FE) [ Balanis , ].…”

An efficient design procedure based on modal‐matching method for axially corrugated dielectric‐rod‐loaded horns of complicated geometries is proposed in this paper. Calculation of the generalized scattering matrix of individual module, which is obtained by dividing the complex horn into simple sections, is carried out. Analytic expressions of power‐coupling integrals between different kinds of waveguides are presented, including those derived initially, which greatly shorten the calculation time. Techniques including the field equivalence principle and the spherical mode expansion are further implemented for radiation pattern prediction. A rexolite‐loaded axially corrugated horn antenna is finally investigated as a numerical experiment, with the frequency range of 17–33 GHz. The results obtained by our method and by commercial full‐wave simulation software are in excellent agreement, but our method is more efficient.
