1. Table contents are derived from 3GPP TS 38.521-1 v15.3.0, table 5.3.5-1.
2. For FR1 Sub-6G bands, NR TDD Bands (n41/77/78/79), only SCS 30KHz is supported, and for other FDD bands, only
SCS 15KHz is supported.
3. For FR2 mmWave bands, only 50MHz and 100MHz bandwidth is supported.
4. This UE channel bandwidth is optional in Release 15.
3.7. Antenna Specification
This appendix describes recommended electrical performance criteria for Sub-6G, GNSS,
and mmWave antennas used with embedded modules.
The performance specifications described in this section are valid while antennas are mounted in the
host device with antenna feed cables routed in their final application configuration.
Note: Antennas should be designed before the industrial design is finished to make sure that the best
antennas can be developed.

Parameter Requirements Comments
Antenna System
(NR/LTE) External multi-band 4x4 MIMO
antenna system (Ant1/ Ant2/Ant3/Ant4)
2
(3G) External multi-band antenna system
with diversity (Ant1/Ant2)
If Ant2 or Ant3 includes GNSS, then it
must also satisfy requirements in Table 3-
7.
Operating Bands —
Ant1
All supporting Tx and Rx frequency
bands.
Operating Bands —
Ant2/3/4
All supporting Rx frequency bands, plus
GNSS frequency bands if Ant2 is used in
shared Diversity/MIMO/GNSS mode.
VSWR of Ant1 and
Ant2
 < 2:1 (recommended)
 < 3:1 (worst case)
On all bands including band edges
