Solutions

Hanyang antenna after continuous research and exploration, broke the limitations of using traditional materials, the use of brass sheet design a greatly reduce the weight of the antenna, axial ratio <2, gain>2dBi, and the maximum gain radiation direction can be debugged, the right-handed polarization radiation field type 0 ° ~ ± 90 ° gain flatness is less than 5dB.

It can make the UAV maintain satellite communication in any attitude, solving the pain point that the UAV can't receive the signal when reversing the direction.

Traditional anti-metal tag antenna, by increasing the spacing between the antenna and the metal, to achieve RF read and write communication, however, this method works on a single tube can, multiple tubes placed densely, adjacent metal will be shielded again on the tag antenna.

In order to solve this problem, Hanyang antenna designed a genus of tubular cavity resonance RFID tag antenna, designed a coupling structure, excitation of the cavity resonance of the metal tube directly produces signal radiation, as a way to easily manage the number of metal tubular and storage.
