汉阳天线经过不断地研究和探索，打破了使用传统材质的局限，采用黄铜片设计出了一款大大减轻重量的天线，轴比<2，增益>2dBi，且最大增益辐射方向可调试，右旋极化辐射场型0°~±90°的增益平坦度小于5dB。 可以使无人机在任何姿态下都能够保持卫星通信，解决了无人机在调转方向时接收不到信号的痛点
传统的抗金属标签天线，通过把天线与金属的间距加大，实现RF的读写通讯，然而，这种方法作用在单个管状物上可以，多个管状物密集摆放的时候，相邻的金属会对标签天线再次产生屏蔽。
为了解决这个问题，汉阳天线设计出了属管状物腔体共振RFID标签天线，设计了一种耦合结构，激发金属管的腔体共振直接产生信号辐射，以此来轻松管理金属管状物的数量及存储。
1. Weight 6~9 grams, the antenna adopts brass sheet structure, which is 1/5 of the weight of traditional ceramic antenna (about 20~30 grams lighter)
2. Axial ratio <2, gain>2dBi, and the maximum gain radiation direction can be adjusted
3. Right-handed polarization radiation field type 0 ° ~ ± 90 ° gain flatness is less than 5dB
Asymmetry between antenna reflective surface and antenna position
Directionally adjustable maximum gain when antenna reflective surface is symmetrical to antenna position
Drones are able to maintain satellite communications in any attitude
Application areas: Intelligent material management of metallic tubular materials
Technical pain points: the traditional anti-metal tag antenna, by increasing the spacing between the antenna and the metal, to achieve RFID read/write communication, however, this method works on a single tube can be, a number of tubes placed densely, as shown in Figure 1, the adjacent metal will be shielded again on the tag antenna.
