“…11). We were inspired by the configuration presented in [16] where the ability of antipodal structure generating CP is presented. The pixel grid geometry is also controlled using parameters l c1 -l c6 , which refer to the number of pixels in the columns, plus additional parameters l c7 -l c13 that determine the rest of the adjusted part of the metal layer.…”

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.

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.
