A broadband substrate‐integrated waveguide (SIW)‐fed endfire metasurface antenna array with improved gain centralisation radiation pattern is proposed in this paper. The metasurface is composed of 3 × 3 rectangular patches distributed on both the upper and lower sides of a single‐layer substrate. For wideband endfire radiation, an open‐end SIW on the metasurface side feeds the antenna. To improve front to back radiation and ration matching characteristics, one C‐shaped slot is etched on the top surface of SIW. Two L‐shaped metal walls composed of metalized via holes are employed to centralize radiation pattern and reduce both the side lobe and back lobe levels. In addition, the gain of the antenna is enhanced more than 1.6 dBi. To validate this design, a 1 × 8 uniform excitation array is proposed and fabricated, containing three SIW T junctions and four Y junctions. The whole dimension is 7.33λ0× 3.82λ0 × 0.06λ0. Measurement results imply that an 7.5 to 13.05 GHz (54%) impedance bandwidth can be achieved with the maximum gain of 14.9 dBi.

“…have been subsequently proposed, which can effectively increase the working bandwidth of the SIW horn antennas. [7][8][9][10][11][12] In modern communication systems, fast fading due to multipath effects seriously affects the overall performance of the system, and one of the most commonly employed methods to combat signal fading is multi-beam technology. Metamaterials are known as artificial media exhibiting unusual electromagnetic properties such as supporting backward wave, negative refractive index 13 and kinds of metamaterials-based antennas and structures have been proposed to achieve novel functions, such as electrically small antennas, electrically large antennas and cavity, low-profile antennas, and multiband antennas, and so forth.…”

This letter presents a novel broadband substrate integrated waveguide aperture antenna with simple structure and beam steering performance. By using the left‐hand and band gap characteristics of the mushroom‐shaped metamaterials, the main beam of the substrate‐integrated waveguide aperture antenna can be easily switched between the back‐fire and boresight directions. Above all, the beam scanning characteristic does not depend on three‐dimensional structures or complex loaded structures, therefore it is a promising technology for designing planar two dimensional beam steering array. Experimental results indicate that the impedance bandwidth of the antenna covers the frequency range from 13.3 to 16.7 GHz and the relative bandwidth is 22.7%. The accordance between the simulated and measured E‐plane radiation pattern of the antenna at three representative frequencies verifies the beam steering capability of the proposed antenna.

“…The gain of a SIW horn antenna can also be improved by producing air layer between the top and bottom surfaces and use of metallic vias and metallic circular patch extension at the aperture end. 15 To achieve high gain, antennas are also arranged in the form of an array. The array structure of the SIW horn antenna is mostly linear as in References 12,16,17.…”

A low-profile three-dimensional substrate integrated waveguide (SIW) horn antenna array with its novel feeding structure is proposed in this article. The feeding element is capable of transforming the wave from one plane to its orthogonal plane. Such type of three-dimensional SIW, H-plane horn antenna design is not available in the existing literature. The design is proposed to provide high gain for radar, 5G, and satellite communication applications. The single SIW horn antenna does not have significant gain at the desired frequencies. When the antenna element is loaded with dielectric the gain improves by 1.4 dB. The antenna elements are further arranged in a box shape, forming a three-dimensional array, which improves the gain significantly. Such structure shows dual band characteristics and provides gain of 11.3 dB at 28.26 GHz and 9.64 dB at 29.41 GHz. The same three-dimensional design when loaded with dielectric at the aperture end also show a dual band behavior and improve the gain further to 12.5 dB at 28.12 GHz and 12.55 dB at 29.28 GHz. The proposed three-dimensional antenna designs are compared to four element linear array designs, and it shows substantial improvement in gain for the desired frequency.
