Advances in miniaturized radio tracking technology are helping to revolutionize the field of wildlife biology, especially with respect to studies of small birds. However, development of antennas for animal tracking applications often fails to formally account for the effects of the animal’s body on signal transmission. This letter describes an electromagnetic phantom that accurately represents a small bird. The phantom is validated with empirical measurements and can be easily scaled to represent larger or smaller bird species.

为鸟类追踪技术提供有效天线的模型设计和验证

小型无线电跟踪技术的进步正在帮助彻底改变野生动物生物学领域，特别是在对小型鸟类的研究方面。然而，用于动物跟踪应用的天线的开发通常无法正式考虑动物身体对信号传输的影响。这封信描述了一个准确代表一只小鸟的电磁幻影。该模型通过经验测量进行验证，并且可以轻松缩放以代表更大或更小的鸟类。
