Abstract
The present invention relates to the communication technology field, more specifically, to a scheme of bilateral antenna. A device for improving the stray isolation between the antennas in the bilateral antenna comprises a plurality of communication modules having an antenna and a power amplification module; at least one of the communication modules further comprises a tuning module. The power amplification module is connected to the antenna directly or through the tuning module. The stray isolation between the communication module and other communication module is improved by adjusting the communication modules comprising the tuning module. This invention increases the stray isolation between the communication modules in different frequency bands, specifically, when a long interval exits between working frequency bands. Consequently, the radiance performance of the bilateral antenna of the mobile termination is satisfied, and the capacity of resisting disturbance between the systems is enhanced.
