求翻译：标签天线要考虑可选天线的类型、阻抗、所处环境、应用距离和方向性等问题，另外还要考虑标签天线要最大限度的为芯片提供信号和能量，以及必须有小的体积和低廉的成本。是什么意思？

Optional tag antenna to consider the type of antenna, impedance, and their environment, applications such as distance and orientation problems, while also considering the tag antenna to maximize signal and provide energy for the chip, and must have a small size and low costs.

Labelling antenna to consider alternative antenna types, impedance, the environment, and the application of distance and direction, and also to take into account issues such as labelling antenna to the maximum extent of available for chip signal and energy, as well as the need to have a small size a

The label antenna must consider may choose the antenna the type, the impedance, to locate the environment, the application is away from and questions and so on directivity, moreover also must consider the label antenna must maximum limit be the chip provides the signal and the energy, as well as mus
