“…As these probes did not fulfill the established specifications, a new approach was taken: inclusion of corrugations around the rectangular aperture of the horns. Finally, the results led to the conclusion that rectangular corrugated horns [8] are the best suited for the application. As mentioned previously, the simulations were carried out using the electromagnetic simulation software MONURBS [7].…”

“…This design, which results in low loss and wide frequency band, is based on air holes drilled on a homogeneous dielectric material. Compared to the previous horn antennas with low sidelobes [2][3][4][5][6][7][8][9], our designs are less demanding, which are thus easier to realize. Therefore, our approach provides a more advantageous recipe for the practical realization of pyramidal horn antennas with low E-plane sidelobes based on coordinate transformation.…”

“…Some efforts have been made to reduce the sidelobe levels of horn antennas [2][3][4][5][6][7][8][9]. State-of-theart techniques for implementing horn antennas having low sidelobe levels are corrugating the interior surfaces [2][3][4], which yields a structure more bulky and difficult to fabricate, applying longitudinal metallic vanes or trifurcations inside the horn to step the electric field in the E plane [5], using optical ray technique [6], employing dispersion engineering of metamaterial properties [7], and design of metasurfaces [8] to taper the aperture distribution.…”

Abstract-Transformation optics is a convenient way to control the pattern of electromagnetic fields. In this paper, using a novel transformation, we propose the design procedure of a horn antenna having low backlobe and sidelobe levels in its E-plane. By applying conformal transformation, the rectangular horn proposed in this paper can be realized with isotropic materials. This proposed antenna can be easily implemented by both ordinary dielectric materials and isotropic graded refractive index (GRIN) materials. In the first proposed design, in addition to the isotropy, homogeneity is furthermore introduced into the horn, and only four kinds of isotropic materials are required throughout. In the second design, it is demonstrated that the designed structure can also be implemented by graded photonic crystals (GPCs) operating in metamaterial regime. They have low loss as well as broad frequency band and are easy to implement. Simulation results are presented to validate the design approach.

“…The rectangular corrugated horn [19] was experimented and it was reported that this antenna type failed to generate the symmetrical beam despite its relatively large size. In [20], the authors proposed a flared rectangular horn corrugated along the -plane flaring walls to achieve the symmetry in theand -planes; nevertheless, the antenna construction is very complicated and the antenna aperture is considerably large. For the rectangular waveguide aperture perpendicular to the direction, the diffracted wave is almost in -plane and it is minimal in -plane.…”

This research presents a triple-aperture waveguide antenna as the primary feed of parabolic reflectors. The proposed antenna is able to rectify the asymmetry and also achieve a symmetrical unidirectional beam through the application of two parasitic coupling apertures. The design of the antenna is that of a rectangular waveguide (radiating aperture) vertically jointed to the two coupling apertures of the same measurement widthwise (i.e., one stacked on top and the other underneath) to achieve the symmetrical beam. The rectangular waveguide is 97.60 mm and 46.80 mm in width (a) and height (b), respectively, to propagate the WLAN frequency band of 2.412–2.484 GHz. Simulations were carried out to determine the optimal antenna parameters and an antenna prototype was subsequently fabricated and tested. The simulated beamwidths in theE- andH-planes at-3 dB were equally 67° (i.e., 67° for both theE- andH-planes) and at-10 dB also equally 137°, while the measured results at-3 dB were equally 65° and at-10 dB equally 135°. The simulation and measured results are thus in good agreement. The simulated and measured antenna gains are, respectively, 8.25 dBi and 9.17 dBi. The findings validate the applicability of the antenna as the prime feed for rotationally symmetric parabolic reflectors.
