TL;DR: In this paper, a wideband horn using printed circuit and substrate integrated waveguide (SIW) technologies has been explored, which is shown to operate over 70% impedance bandwidth showing a consistent three-dimensional symmetric broadside radiation with an 8.7-19-dBi peak gain.
Abstract: A wideband ridged horn using printed circuit and substrate integrated waveguide (SIW) technologies has been explored in this letter. A stepped flaring has been introduced in E-plane by adding multiple substrate layers, which is further loaded by a pair of E-plane flared balanced ridges to increase its operating bandwidth. The proposed technique is free from the requirement of any chemical glue or adhesive. A conventional SIW-based H-plane flaring is used. This horn is found to operate over 70% impedance bandwidth showing a consistent three-dimensional symmetric broadside radiation with an 8.7–19 dBi peak gain.

TL;DR: In this paper, a gap waveguide-based H-plane horn antenna with air-filled features is proposed. But the antenna is not suitable for high frequency bands and the gain varies between 8.5 and 12 dBi.
Abstract: H -plane horn antenna using gap waveguide technology is proposed. The advantage of this technology is its air-filled feature, which improves the impedance matching compared with substrate integrated waveguide (SIW) horn antennas. Corrugated walls as soft surfaces are used on the outer surfaces of the upper and lower horn plates, which act as barriers around the aperture of the antenna and reduce its backlobe levels. The bandwidth of the antenna for $| {{S_{11}}} |$ < -10 dB is 19–28 GHz and the gain varies between 8.5 and 12 dBi. The total efficiency is better than 88% in the operation bandwidth. This structure has the capability of easily integrating with other planar microwave components. As a demonstration, a coupled-resonator filter is integrated with the antenna to select the desired frequency band and cancel the out-of-band harmonics. For the proof of concept, a prototype model is fabricated and tested, where measurement data agree well with the simulation results.

TL;DR: In this article , the authors demonstrate a coaxial transmission line-to-substrate integrated waveguide (CT-SIW) transition using aperture-coupling approach, which broadens the bandwidth and reduces the transition insertion loss.
Abstract: The letter demonstrates a coaxial transmission line-to-substrate integrated waveguide (CT-SIW) transition using aperture-coupling approach. The method broadens the bandwidth (BW) and reduces the transition insertion loss (IL). Two coaxial line supports with apertures for coupling are attached at the ends of substrate integrated waveguide (SIW). The copper inlaid of the apertures increases coupling of the coaxial line to SIW and can be controlled by the aperture length and the length of the line wire put in the aperture. The transition was designed, fabricated, and experimentally evaluated. The transition provides the measured 10 dB return loss (RL) fractional BW (FBW) of 104.3%, and 15 dB RL (FBW) of 78.06%. The IL of 0.37 to 0.87 dB at 19.63–62.7 GHz frequency range was obtained. The measured results are well correlated with the simulated ones.

TL;DR: In this paper, a linearly and circularly polarized single-layer SIW horn antennas with nearly equal half power beamwidths in principal planes for the 24 GHz ISM band are designed.
Abstract: In this paper, linearly and circularly polarized single-layer Substrate Integrated Waveguide (SIW) horn antennas with nearly equal half power beamwidths in principal planes for the 24 GHz ISM band are designed. The uniqueness of the solution lies in the application of a pixelated structure to the design of these SIW horn antennas. For the design, a novel heuristic algorithm called Binary Ink Stamp Optimization is proposed. At first, the ability of the proposed algorithm is proved over fifteen benchmark functions and compared with the results of six state-of-the-art optimization algorithms. Then, the novel algorithm is exploited for the design of the pixelated part of the antennas. The antennas are manufactured using low-cost 3D printing technology. The experimental results prove that the linearly polarized antenna has a reflection coefficient below −18 dB in the whole 24 GHz ISM band. At the center frequency of this band, the antenna gain is 14.2 dBi, and the level of side lobes is below −15 dB in E and H-planes. In addition, E and H-plane half power beamwidths are 26.5° and 25°, respectively. The circularly polarized antenna radiates a right-hand circularly polarized (RHCP) wave, the reflection coefficient, and axial ratio are below −12 dB and 3 dB in the whole 24 GHz ISM band, respectively. At the center frequency of this band, the antenna gain is 8.9 dBi and the level of side lobes is below −7.4 dB in both principal planes. Further, the half power beamwidths in principal planes are 30.6° and 33.4°, respectively.

TL;DR: In this paper , a circularly polarized Substrate Inte-grated Waveguide horn antenna with nearly equal beamwidths in principal planes is presented, which is designed to operate at the 24 GHz ISM band.
Abstract: In this paper, a circularly polarized Substrate Inte-grated Waveguide horn antenna with nearly equal beamwidths in principal planes is presented. The antenna is designed to operate at the 24 GHz ISM band. The antenna parameters enhancement is achieved using a pixelization strategy applied to its topology. For the design, a heuristic algorithm called Binary Ink Stamp optimization is exploited. The simulated proposed antenna provides a -10dB reflection coefficient bandwidth of 21.4%, a 3dB axial ratio bandwidth of 4.1% and a gain 9.4 dBi. A difference between half-power beamwidths in principal planes over the 24 GHz ISM band is below 1°.

TL;DR: In this article, a dielectric loaded substrate integrated waveguide (SIW) H-plane sectoral horn antenna has been proposed and two antennas with rectangular and elliptical shaped loaded dielectrics were designed and fabricated.
Abstract: A dielectric loaded substrate integrated waveguide (SIW) H-plane sectoral horn antenna has been proposed in this paper. The horn and the loaded dielectric are integrated by using the same single substrate resulting in easy fabrication and low cost. Two antennas with rectangular and elliptical shaped loaded dielectrics were designed and fabricated. These antennas have high gain and narrow beamwidths both in the E-plane and in the H-plane. The results from the simulation and those from the measurement are in good agreement. To demonstrate applications of the array, the small aperture elliptical dielectric loaded antenna has been used to form an array to obtain higher gain and to form a one-dimensional monopulse antenna array.

TL;DR: In this article, a transition printed on the same SIW substrate is proposed to improve the matching performance of SIW horn antennas in the Ku-band with a substrate thinner than λ 0/10.
Abstract: The substrate integrated waveguide (SIW) technology allows to construct several types of commonly used antennas in a planar way. However, some practical constraints limit their performances when frequencies below 20 GHz are considered. In the case of SIW horn antennas, the available substrates are much thinner than the wavelength yielding to poor matching and undesired back radiation. In this paper, an innovative structure to overcome these limitations is presented. It consists of a transition printed on the same SIW substrate, which improves both the radiation and the matching performances of conventional SIW horns. The horn shape is also further optimized by reducing its dimensions required for a given directivity. This is obtained by modifying the horn profile in order to effectively combine different TE modes. Guidelines are provided to design this type of thin and compact SIW horn antenna. They were applied to manufacture a prototype in the Ku-band with a substrate thinner than λ0/10. Measurement results validate the proposed concepts showing excellent performances.
