Details This prototype 2.6-m diameter metal-mesh antenna reflector represents a big step forward for the European space sector: versions can be manufactured to reproduce any surface pattern that antenna designers wish, something that was previously possible only with traditional solid antennas. Webb8 mars 2024 · The conductive reflector 138 is longer than the conductive antenna 130 in the first direction X, and the conductive reflector 138 is wider than the conductive antenna 130 in the second direction Y. The first portion 131 of the conductive antenna 130 has a rectangular shape in the third plane and includes slots 133 and 134 as shown in FIGS.
WebbA common type of array antenna, a reflective array UHF television antenna.This example consists of eight dipole driven elements mounted in front of a wire screen reflector. The X-shaped dipoles give it a wide bandwidth to cover both the VHF (174–216 MHz) and UHF (470–700 MHz) TV bands.
