Description
Technical Field

In a north american operator, the LTE band supports B2/4/5/12/14/66/71, and Carrier Aggregation (CA): b2+5, B2+12, B4+12, B2+4, B2+ 71.
In the conventional rf architecture, referring to fig. 1, a main set antenna 11 is connected to a main set switch 12, and the main set switch 12 is connected to a transceiving port of a transceiver 14 through a main set path 13. The diversity antenna 15 is connected to a diversity switch 16, a frequency divider is integrated in the diversity switch 16, and the diversity switch 16 is connected to a receiving port of the transceiver 14 through a diversity path 17.
Because the frequency divider is integrated in the main set switch, the frequency divider can separate intermediate frequency signals from low frequency signals, and ensures that the low frequency signals and the intermediate frequency signals are simultaneously input into the transceiver to realize downlink carrier aggregation. Similarly, diversity also uses frequency divider to implement L + M band carrier aggregation.
The mobile phone antenna can generally realize 3 resonance points, namely low frequency, intermediate frequency and high frequency, wherein the bandwidth of the low frequency is narrowest, and the middle-high frequency resonance points can basically cover the current frequency band requirement. Therefore, if the frequency bands of low frequencies are more and are close to two limits of low-frequency spectrum resources, the too-narrow low-frequency resonance bandwidth is difficult to cover all frequency points, and the debugging result of the antenna at this time is some low-frequency OK and some low-frequency NOK.
For a certain north american operator, there are special requirements for TIS and TRP on a human hand model, so that when the sample is held by hand, the standing-wave ratio of the antenna is affected, so that the performance of low frequency is worse, the resonance bandwidth of low frequency is shifted, and the test results of TIS and TRP are poor.
