| Summary: | 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. |
