- Scalable high-gaussicity split-block diagonal horn antenna for integration with Sub-THz devicesPublication . Santos, H. M.; Lima, E. D.; Pinho, Pedro; Pessoa, L. M.; Moro-Melgar, D.; Salgado, H. M.In this paper we propose a high-gaussicity spline-profiled horn antenna, which is scalable in length and aperture to achieve higher gains whilst retaining a high Gaussian efficiency. A novel approach is used where a PSO is used for optimizing the spline, using the gaussicities at the operating frequencies as the objective function, which further improves side-lobe level and cross-polarization when compared to the state-of-the-art. With the proposed method, which was validated through FEM simulations in HFSS, reflection coefficients below -15 dB, gains greater than 25 dBi and gaussicities above 91% were obtained in the entire WR-3 band.
