Abstract
The layout of multi-antenna loops in this invention comprises: a plurality of antenna loops, wherein one terminal of each antenna loop is electrically coupled with an antenna switch and the other terminal is electrically connected to a ground wire. All antenna loops are symmetrical antenna loops each of which contains a plurality of n-shaped sections to form sawtooth-shaped regions and compound into a plurality of dummy closed regions. If the symmetrical antenna loops are in-phase state, the plurality of sawtooth-shaped regions consist of the plurality of n-shaped sections with the non-interlacing method; if the symmetrical antenna loops are oppositephase state, the plurality of sawtooth-shaped regions consist of the n-shaped sections with the interlacing method.
