The new iPhone models are said to use at least two antenna modules like the iPhone X but with support for 4x4 MIMO.
Antenna design upgrade a key factor in anticipated boost to LTE transmission speed in new 2H18F iPhone models. As a LTE antenna FPCB material, LCP is superior to PI in properties related to high-frequency, thermal performance and moisture resistance. We predict 2H18 new iPhones will be equipped with two LCP LTE antenna modules same as iPhone X or more, but with higher specs to support 4x4 MIMO standards.
Kuo previously predicted that Apple will upgrade baseband chips from Intel’s XMM 7480 and Qualcomm's MDM 9655 to Intel’s XMM 7560 and Qualcomm's SDX 20. Both new chips support 4x4 MIMO technology resulting in a significant increase to LTE transmission speeds.
Apple is said to be working on three new iPhones for 2018 - a 6.5-inch OLED model, a 5.8-inch OLED model, and a 6.1-inch LCD model.
