What input polarization provides the maximum jamming signal strength for a horizontally polarized receiving antenna?

The maximum jamming signal strength for a horizontally polarized receiving antenna is achieved when the jamming signal is also horizontally polarized. This is due to the principle of polarization matching in antennas, where the efficiency of signal reception is highest when both the transmitting and receiving antennas are aligned in the same polarization.

When a horizontally polarized antenna receives a horizontally polarized signal, it can convert the maximum amount of the incoming electromagnetic waves into electric currents, resulting in stronger signal reception. In contrast, utilizing vertical, slant 45-degree, or circular polarizations would lead to significant losses in signal strength, as the orientation of these signals does not match the orientation of the antenna, resulting in decreased coupling and less effective signal reception. This highlights the importance of aligning polarization for optimal performance in electronic warfare scenarios.
