Apple is the most known brand for creating quality hardware for its product line. 5G is on top spec list for all the smartphone manufacturers in 2020. Apple being the biggest brand is looking to build its own 5G antenna as Qualcomm’s QTM-525 millimeter-wave antenna module does not fit the new design that Apple wants for its iPhone in 2020.
Apple’s history is not good with building its own antenna, we all have seen the Antennagate that was there at the time of iPhone4.
Apple is working on another design that uses both Qualcomm Snapdragon X55 5G modem chip and antenna.
