GPS Antenna has failed

Apple Technicians have confirmed through a series of hardware tests that the "GPS Antenna" has failed in this iPhone 13 mini. I am looking to repair this myself but am unable to determine which of these is what Apple technician is calling "GPS Antenna"

• 802.11ax Wi‑Fi 6 with 2x2 MIMO
• 5G (sub-6 GHz and mmWave)
• Gigabit LTE with 4x4 MIMO and LAA
• Bluetooth 5.0
• Apple-designed U1 Ultra Wideband chip for spatial awareness
• NFC

Can anyone help me to identify which part I need for this repair?

thank you,

-J
