“…For aperture sizes up to 2λ0, many candidate antenna solutions with excellent RF performance and low profile have been developed. These solutions include the Scrimp horn [4,5], the short backfire antenna [6][7][8][9] or the stacked Fabry-Perot cavity antenna [10]. However, for the aforementioned radiating elements, the bandwidth and the aperture efficiency decrease steadily as the radiating aperture is increased.…”

A novel compact and highly efficient dual-polarized horn-like antenna is presented. It exploits a radiating aperture that is fed by four smaller waveguides via a quad-furcated junction. The antenna also comprises the full feed network for the feed waveguides including an integrated 4-way orthomode power divider. Design principles are described in detail and illustrated by means of an example involving an antenna with aperture size of 2.6λ0×2.6λ0 (λ0 the wavelength at the central frequency of operation) intended primarily for Geostationary Orbit (GEO) satellites. The antenna feed was designed to comply with the Additive Manufacturing rules and exhibits aperture efficiency levels close to the theoretical maximum ones over the entire transmit Ku band (10.7 -12.75 GHz), while at the same time its profile is highly compact (6.4λ0). The measured results of a prototype 3D-printed in Selective Laser Melting (SLM) verified experimentally the calculated high aperture efficiency (over 90%). The total antenna feed attains return loss > 19 dB and maximum cross-polarization isolation (XPI) > 24 dB over a bandwidth of 18%. In light of the favorable electrical performances and compact size, the proposed solution constitutes an appealing alternative to profiled (or spline) horns for satellite antenna systems used either as reflector feeds or direct radiating arrays.

“…Compact Potter horns and variants [5], [6] offer excellent performance with a total horn length of a few wavelengths (typically larger than as reported in [6]). Short backfire antenna elements [7], [8] but their performance in aperture efficiency [9], [10,Eq. (2)] is limited to aperture sizes smaller than .…”

Abstract-The performance of compact linearly polarized Short Circular Ring-loaded horn with Minimized cross-Polarization (Scrimp) horns with different aperture sizes is first evaluated using an in-house finite-difference time-domain (FDTD) computer-aided design (CAD) tool. Then, a very short hexagonal Scrimp horn with an aperture size of is designed in -band; its height is only. The experimental results demonstrate that the aperture efficiency is higher than 80% with a reflection coefficient lower than 17 dB over a 12.6% frequency bandwidth. Radiation patterns of excellent quality are measured with a cross-polarization level lower than 28 dB over the entire bandwidth. These antennas are very attractive candidates for high-power focal array configurations in multifeed systems.
