The array flat panel 5.8G receiving antenna is a directional circularly polarized antenna based on advanced array technology. It adopts a glass array design and uses an array of multiple coupled patches to achieve significantly higher gain. Although its relatively narrow beamwidth may not be suitable for general FPV applications, this antenna performs very well in long-distance flights of -country and fixed-wing aircraft, especially in open and unobstructed outdoor environments, it can provide excellent signal reception and stability, ensuring the reliability of long-distance flight. In addition, the antenna also has good radiation efficiency and very good axial ratio, as well as extremely low side lobes, ensuring that the energy is concentrated in the main lobe, further improving the long-distance performance. High gain (14.0 dBi measured) Directional circular polarization Wide bandwidth (950 MHz measured) Good signal matching Excellent axial ratio High radiation efficiency Low side lobes Designed for long-distance navigation Glass array Main applications: FPV Drone long-distance flight Fixed-wing aircraft long-distance flight More application scenarios: Fixed-point video transmission Long-distance data transmission Ground station receiving antenna FPV racing in specific environments Dimensions:300 x 150 mm Weight:148.5g Center frequency: Simulation: 5.8 GHz Measured: 5.8 GHz + 100 MHz Bandwidth: Simulation: 660 MHz (5.47-6.13 GHz) Measured: 950 MHz 100 MHz(Feed network loss increases bandwidth) Matching: Simulation: S11 Less than -30 dB, VSWR Less than 1.065 Measured: S11 Less than -20 dB, VSWR Less than 1.22(At center frequency) Axial ratio: Simulation: 1.05 (0.38 dB) Measured: 1.10 (0.83 dB)(Average over beam width) Antenna gain: Simulation: 14.4 dBi Measured: 14.0 dBi Half power beamwidth Simulation: 30 Measured: 30(Horizontal and vertical) Radiation efficiency: Simulation: 75% Measured: 74% Specifications:A: Inner Needle Color:Blue Material:ABS Package Contents: 1 * 5.8G 14DBI FPV Antenna Only the above package content, other products are not included.
