Here is a breakdown of where you can find the antennas on the iPhone 13: 1. Cellular Antenna: The primary cellular antenna is typically located at the bottom of the iPhone 13, near the Lightning port. This antenna is responsible for receiving and transmitting cellular signals, allowing you to make calls, send texts, and use mobile data. The most noticeable design change on the 2020 iPhone lineup from the iPhone 11 series is the flattened sides.
