5G LPDA Antenna: The Ultrawideband Solution for Global 4G/5G Convergence- Our Technological Leaps
RF element redefines hybrid network deployment with our industry-leading 5G LPDA antenna, extending operational bandwidth from conventional 698-2700MHz to 698-4200MHz. This single-antenna solution eliminates multi-antenna setups while covering:
4G/LTE bands (698-960MHz)
5G NR bands (3300-4200MHz n77/n78)
Legacy 2G/3G frequencies
Technical Innovations
1. Bandwidth Expansion Technology
| Parameter | Standard LPDA | RF element LPDA |
|---|---|---|
| Frequency Range | 698-2700MHz | 698-4200MHz |
| Bandwidth Ratio | 3.9:1 | 6:1 |
| Average Gain | 8.5 dBi | 9.2 dBi |
| VSWR | ≤1.8:1 | ≤1.5:1 |
| PIM (2x20W) | -150 dBc | <-155 dBc |
2. Tri-Impedance Dipole Architecture
Low-Band (698-960MHz): Tapered-arm folded dipoles
Mid-Band (1700-2700MHz): Multi-slot coupled dipoles
High-Band (3300-4200MHz): Laser-cut micro-dipoles
