It depends on the frequency, not the type of modulation.
However, in view of the wavelength of medium waveband transmissions and h.f. transmissions the antennas are always horizontal and therefore so is the polarisation.
A single polarized antenna is designed to transmit or receive electromagnetic waves with a specific polarization, either horizontal or vertical. This means that the electric field of the emitted or received signal oscillates in only one plane. Single polarization is often used in communication systems to enhance signal quality and reduce interference, as both the transmitting and receiving antennas need to match in polarization for optimal performance.

Linear vertical or horizontal polarization is normally used in microwave transmission. Reasons: Circularly polarized antennas are more complex and more expensive, because they are actually double polarized antennas, i.e. a combination of horizontal and vertical polarizations. Rain attenuation is lowest when the polarization is vertical. Therefore longer hops can be built if circular polarization is avoided.
No. They can be circularly polarized with the correct phasing harness, or used as a way to switch between horizontal and vertical polarization with one antenna.

The polarization vector of an electromagnetic wave indicates the orientation of the electric field oscillations. It is significant because it determines the direction in which the wave's energy is transmitted and affects how the wave interacts with materials and antennas. Different polarizations can have different effects on communication systems and signal reception.

Polarization is used in sunglasses to reduce glare from sunlight, in 3D glasses for viewing stereoscopic images, in liquid crystal displays (LCD) for electronic devices, and in optical communication systems to transmit and receive information.
Its an antenna that can operate in vertical as well as horizontal polarization. Dual polarized antennas are often used in 802.11n devices to enable multi-thread communication. This enables the device to transmit data on one polarization and receive data on the other simultaniously. The advantage of this is that multi-thread communication can be achieved with the use of one antenna instead of using two independent (and opposite polarized) antennas for the same result. Obviously all the networking equipment in the wireless network must be multi-thread complaint for this to work.
