Polymers intended for microwave antennas should have a dielectric constant between 1.5–3.0 and tan δ loss factor less than 0.001 for high-gain, small beam-width operation. Desirable antenna properties are obtained by polymerizing the monomer using UV and γ -radiations compared to polymerization with the use of initiators. The polymer should be able to withstand shock,vibration and high ambient temperature.Teflon has proved to be the polymer of choice followed by polystyrene, perspex, nylon, polypropleyne and polyacetal.
