5G radomes are essential for protecting antennas from environmental factors while maintaining signal integrity. Leading manufacturers offer advanced radome solutions with minimal signal interference. This guide explores the top companies producing high quality 5G radomes. The specifications of 5G NR massive mimo antenna radome and materials used by manufacturers of antenna radome are also mentioned.
What is 5G Antenna 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.

The figure depicts cross section of radome around antenna panel housing antenna array along with other layers such as FEM (Front End Modules), RFICs and so on. Radome material should be anti-temperature, water proof, anti-aging and weather resistant.
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.
