The radiation efficiency and isolation curve of 85mmX8.7mm, 87mmX7mm, 90mmX6mm, it can be seen in the drawings that above-mentioned
Under size, the radiation efficiency and isolation of antenna meet benchmark requirement, that is to say, that relative to not set isolated location 40
For antenna, when first size is chosen to be 79mm, 85mm, 87mm, 90mm, the second size it is settable as 9mm, 8.7mm,
7mm, 6mm small as far as possible size, alternatively, first size is settable when the second size is chosen to be 9mm, 8.7mm, 7mm, 6m
The size small as far as possible such as 79mm, 85mm, 87mm, 90mm.
As described above, by the way that isolated location 40 is arranged between two radiators, so that antenna is meeting isolation
Under conditions of radiation efficiency, size can be arranged smaller, accordingly, the antenna windows of metal shell can open up it is smaller, into
