The module supports the AGPS/GPS function, so the system equipment needs to add the GPS antenna. The design of GPS
antenna is consistent with that of the main antenna, and its efficiency can be 3dB lower. The isolation between the main
antenna and the diversity antenna is required to be greater than 12dB. The difference between Rx TIS and the TIS of main
antenna should be within 6dB.
The antenna index is divided into the Passive index and Active index. The Passive index includes S11, efficiency, gains,
radiation pattern and polarity, which can be used as the parameter measuring the performance of the antenna itself. The
Active index is also called the OTA index, including TRP (all-round radiation power), TIS (all-round receiving sensitivity),
radiation pattern, which is an important index measuring the radiation performance of the whole set (including the antenna,
module, main board).
