[TR] 트리플 피드 패치-1 5.8GHz 9.4dBi 지향성 원편파 FPV 안테나

Tarot Triple Feed Patch-1 5.8GHz 9.4dBi Directional Circular Polarized FPV

FPV Goggle용 고감도 Tripple Patch-1 9.4dBi 지향성 서클 안테나 세트.

- Center frequency: 5.8 GHz
- Bandwidth: 660 MHz (5.47 ~ 6.13 GHz)
- Matching: S11 < -20 dB, VSWR < 1.22 (at center frequency)
- Axial ratio: < 1.3
- Antenna gain: 9.4 dBi
- Half power beam width: 55° (horizontal and vertical)
- Radiation efficiency: 83.5%
- Diameter of large disk : 5.94cm
- Diameter of small disk: 2.46cm
 

- Good radiation efficiency. Most FR4-based patches have terrible efficiency because FR4 is very lossy at 5.8 GHz
- Good axial ratio, not just directly perpendicular to the patch but also off-center
 

Note: The PCBs must use 1.0 mm thickness FR4 material
