The 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, resulting in significantly higher gain. This antenna is not recommended for general FPV use since the beam width is rather narrow, however it performs brilliantly for long-range flying. Like the original antenna, it is also a hybrid antenna so you can switch between Left-Hand Circularly Polarised (LHCP) and Right-Hand Circularly Polarised (RHCP). Features: Good radiation efficiency. Most FR4-based patches have terrible efficiency because FR4 is very lossy at 5.8 GHz. Additionally, 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. Exceptionally good axial ratio, not just directly perpendicular to the patch but also off-center. High gain, though not as high as the theoretical gain of an array with 7 elements. This is because maximizing the gain would result in high sidelobes and a poor axial ratio. Supports both LHCP and RHCP Specification: Center frequency: 5.8 GHz Bandwidth: 660 MHz (5.47 – 6.13 GHz) Matching:S11 < -30 dB, VSWR < 1.065 (at center frequency) Axial ratio: < 1.05(0.38db) Antenna gain: 14.4 dBi Half power beam width: 30° (horizontal and vertical) Radiation efficiency: 75% Package contains: 1x 150mm Triple Feed Patch Array Antenna (pick from either Red or Black) 1x Semi Rigid SMA Extension
