What is 5G Antenna Radome & its material: Top Manufacturers

A 5G antenna radome is a protective enclosure that shields antennas from environmental factors such as rain, UV exposure, dust, wind and temperature fluctuations while allowing radio frequency signals to pass with minimal attenuation. Common radome materials include fiberglass reinforced composites, PTFE, polycarbonate, ABS and advanced low loss dielectric materials optimized for 5G network performance. Top manufacturers are Pacific Radomes Inc., Infinite Technologies Incorporated and Diab Group. 5G radomes are essential for protecting antennas from environmental factors while maintaining signal integrity.

What is Radome?

The protective enclosure around the antenna used to protect itself from harsh environments is known as radome. It attenuates EM signals during transmission and reception minimally. The radome used to protect 5G massive mimo antenna array is known as 5G antenna radome. 5G NR supports different frequency bands sub-6 GHz and above 6 GHz in mmwave region.

Antenna Radome Material

Following materials are considered for antenna radome as per specifications.

• PVC, FRP and ASA are used for sub-6 GHz radome materials. These materials offer good mechanical, thermal and dielectric properties below 6 GHz. For these materials, dielectric losses increase significantly for mmwave frequencies and hence thickness of material is appropriately chosen to compensate for these losses.
• The other alternatives to radome materials include syntactic foams, prepregs or other composite constructions which perform better at high frequencies.
• Following table mentions selection of materials used for antenna radome.

Material	Brand	Dielectric constant	Loss Tangent
Epoxy/Fiberglass	G10, FR4	4.9	0.0190
Acetal	Delrin, Celon	3.7	0.0050
ABS	Lustran, Cycolac	3.23	0.0200
Nylon 6/6	Zytel	3.2	0.0210
Polyetherimide	Ultem	3.15	0.0013
Polystyrene	Styron	2.75	0.0005
Polycarbonate	Lexan	2.35	0.0100
UHMWPE	Dyneema	2.2	0.0004

Permittivity, loss tangent and radome material thickness must be selected carefully in conjunction with distance to antenna elements in order to enable optimal performance.
