Yes, it is possible to optimize the performance of an antenna by using an armor or shield. An armor or shield is used to protect the antenna from external electromagnetic interference (EMI) and radio frequency interference (RFI), which can improve its performance and increase its resilience.
An armor or shield is placed around the antenna and is made of a conductive material, such as aluminum or copper. The conductive material helps reflect or absorb external electromagnetic waves, preventing them from propagating to the antenna and causing signal interference.
Additionally, a shield also helps reduce the electromagnetic radiation emitted by the antenna, which can be beneficial in applications where low radiation emission is required; But be careful: this must be well calculated for it to work, because if you do it without a study you can lose the gain of your antennas.
