FPV Antennas 5.8GHz
GEPRC Triple Feed Patch 5.8 14dBi SMA antenna
FPV → FPV 5.8GHz → FPV Antennas 5.8GHz → Triple Feed Patch Antennas → GEPRC Triple Feed Patch 5.8 14dBi SMA antennaThe Triple Feed Patch Array antenna is a directional circularly polarized antenna based on the original Triple Feed Patch antenna. It uses an array of seven coupled patches to achieve significantly higher gain. Since the beam width is quite narrow, this antenna is not recommended for general FPV, but it performs very well for long-range flights.
Description:
Brand name: GEPRC
Item number: Triple Feed Patch Array-1
Connector: SMA, RP-SMA (Optional)
Simulation diagram:
Measured Figure:
VAN measurement:
Features:
* Good Radiation efficiency. Most FR4-based patches are very efficient because FR4 is very lossy at 5.8 GHz. In addition, most array antennas have higher losses in the feed network. This design uses coupled patches to keep the feed network simple and reduce these losses.
* Good shaft ratio, not only perpendicular to the patch but also eccentric.

* Good shaft ratio, not only perpendicular to the patch but also eccentric.
* High gain, but not higher than the theoretical gain of an array with 7 elements. This is because maximizing the gain results in high side lobes and poor axial ratio.
* Very low side lobes, almost all of the energy is concentrated on the main lobe. This will increase the width of the main lobe but will increase some gain.
