A positioning foot ring includes a ring-shaped body and a base of the GPS module detachably assembled on the ring-shaped body, and the surface of the ring-shaped body is provided with more than one metal sheet, which can be used as an antenna for the GPS module and/or other electronic components Or pick up the area. In this way, the positioning foot ring makes full use of the surface area of the ring body, which is conducive to miniaturization and light weight, can reduce the pigeon's flight load, and maintain good convenience and efficiency.一種定位腳環，包含環形本體，以及GPS模組可拆卸的組裝於該環形本體的基座，該環形本體表面設有一個以上金屬片，能夠作為該GPS模組及/或其他電子元件的天線或接地區。藉此，定位腳環充分利用環形本體的表面積，有利於微小化與輕量化，可減少鴿子飛行負重，而且維持良好的使用便利性與效能。
