| Zusammenfassung: | The invention discloses a 12 spiral array measurement and control antenna, relating to a measurement and control antenna device in the field of unmanned aerial vehicle measurement and control antennas. The 12 spiral array measurement and control antenna comprises twelve 14.5-circle single-winding, parasitic, conical spiral unit antennas, two one sixth non-equiamplitude power dividers, a sum and difference device, fourteen equi-phase low-loss coaxial cables, an unequal space main skeleton with a box section, a cable socket, a supporting rod and the like. The spiral array measurement and control antenna disclosed by the invention has the characteristics of high gain, low side lobe, wide frequency band, good circular polarization property and matching property, small volume, light weight, easiness in installation, suitability for vehicle-mounted and long-distance low-elevation tracking and the like, and is particularly suitable for being used as the measurement and control antenna device in the field of unmanned |
