Transmission radiators come in various forms, each tailored for specific applications. The most common types are dipole antennas, monopole antennas, and loop antennas. Dipole antennas, consisting of two conductive elements, are widely used due to their simplicity and effectiveness. They are often employed in radio broadcasting and amateur radio operations. Monopole antennas, which consist of a single conductive element, are typically mounted perpendicularly to a conductive surface and are commonly used in mobile communication. Loop antennas, characterized by their circular shape, are used in specialized applications like RFID systems and certain types of scientific measurements.

One of the most groundbreaking developments in stealth chassis technology is the use of metamaterials—artificial materials designed to manipulate electromagnetic waves. These materials can alter the way radar signals interact with an object, effectively bending or redirecting waves around it. Incorporating metamaterials into a chassis can significantly reduce its RCS, making it extremely difficult for radar systems to detect. This innovation marks a significant leap forward from traditional stealth techniques, which often rely on shape and surface coating alone.
