LTE 3G 4G Antenna Applications
Antenna Isolation Design Requirements
1. Antenna Isolation
For two or more antennas with overlapping frequency bands in space, antenna isolation is defined as the ratio of a signal received by one antenna to the signal transmitted by another antenna. The isolation depends on the radiation pattern of the antenna, the spatial distance of the antennas, etc.
Antenna isolation improvement is to take measures to minimize the impact of various interference on the receiver.
The isolation between antennas can be increased by:
⚫ Increasing the physical separation between the antennas
⚫ Placing antennas working in adjacent bands orthogonally to each other
⚫ Having the antenna’s peak radiation in different or opposite directions
⚫ Changing the antenna trace implementation method (such as length, width)
Additionally, adding a filter in the RF signal path will help to improve the desired signals’ suppression effect on those unwanted signals, thus abating the interference caused by insufficient antenna isolation.
2. Isolation between 3G/4G Antenna and GNSS Antenna
⚫ The isolation between a 3G/4G antenna and a GNSS active antenna should be at least 10dB.
⚫ The isolation between a 3G/4G antenna and a GNSS passive antenna should be at least 15 dB.
It is recommended to add a filter between a GNSS antenna and a module to suppress interference from other antennas.
3. Isolation Design of Other Antennas
⚫ The isolation of other antennas should be at least 15 dB.
⚫ Isolation design is vital to antennas working at similar frequencies. When two antennas are used synchronously, one of them is recommended to be designed to support only part of the bands to ensure better performance.
For example, for a device supporting GSM B1/B3/B5/B8 & LTE B1/B3/B7, the main antenna should support all the bands while the diversity antenna only needs to support LTE bands.
