GEPRC Triple Feed Patch Array 5.8G circularly polarized Antenna For Long Drone RC Drone VTX Video Transmitting

Brand:GEPRC

Center frequency: 5.8 GHz
Bandwidth: 660 MHz (5.47 - 6.13 GHz)
Match: S11 < 20 dB, VSWR < 1.22 (at center frequency)
Axial ratio: < 1.3
DBi antenna gain: 14
Half power beam width: 55 degrees (horizontal and vertical)
Radiation efficiency: 83.5%

These values are based on simulations, and the actual measurements are as follows(they are very similar).
Because of the change in the FR4 dielectric constant, the center frequency may be shifted between batches.
Also, not all FR4 brands have the same dielectric constant.
Frequency conversion to 100 MHz is normal.
