Technology Innovation Points:

1. Weights10~20g,The antenna is made of brass sheet structure, which is 1/10th of the weight of conventional ceramic antenna.(A single antenna reduces the weight by about 40-60 g, and at least 2-5 positioning antennas are installed on one drone, which means a drone can reduce the weight by 80-300 g for each.)

2. Axis ratio <2, gain >2dBi, and maximum gain radiation direction adjustable

3. Gain flatness less than 5dB from 0° to ±90° for right-handedly polarized radiated field type

Advantages of weight reduction in UAV applications:

1. Enhanced range (A cell phone battery weight is about 30 grams, so the reduced weights of the antenna increases the capacity of the drone's battery)

2. Reduce take-off weight

3. Increased ballistic loads (a reduction in antenna weight increases the ballistic load by the corresponding weight)
