Realacc Triple Feed Patch Directional Circular

Electronics & Electricals, InternationalBanggood

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

Features:
Good radiation efficiency. Most FR4-based patches have terrible efficiency because FR4 is very lossy at 5.8 GHzGood axial ratio, not just directly perpendicular to the patch but also off-center
Note: The PCBs must use 1.0 mm thickness FR4 material
Package included:
1 x Realacc Triple Feed Patch-1 5.8GHz 9.4dBi Directional Circular Polarized FPV Antenna
1 x Extended cable
1 x SMA Feamale to RP-SMA Male adapter connector

The Triple Feed Patch antenna is a directional circularly polarized antennaGood 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.
Mini version with 45mm diameter
This antenna is working very well and has very good build quality. Works very well on my google. Increase the video transmission quality Excellent directional antenna that can be used both as rhcp and lhcp. For optimal performance you will also need 50 ohm terminator .
