. It’s a tiny antenna array, roughly the size of a penny, that features four antennas that can (with the help of Qualcomm’s algorithms) accurately point toward the nearest 5G tower. It can even bounce signals off of surrounding surfaces. The QTM052 is designed to be small enough that device manufacturers will be able to embed it into the bezel of a phone. Qualcomm’s X50 5G modem is already designed to support up to four of the antenna arrays, one for each side of the phone, allowing for 16 total antennas and ensuring that no matter how you hold your phone, the signal won’t get blocked.
