Abstract:
1. A decoupling circuit, for enhancing isolation of two monopole antennas, wherein the two monopole antennas substantially symmetrically stand on a bottom and a gap is formed between the two monopole antennas, the decoupling circuit comprising: a grounding element, located on the bottom and electrically connected to a ground terminal; a connection bar, substantially perpendicular to the bottom, comprising a first terminal electrically connected to the grounding element and a second terminal extending to the gap; a first branch, extending from the second terminal of the connection bar to a first monopole antenna of the two monopole antennas; and a second branch, extending from the second terminal of the connection bar to a second monopole antenna of the two monopole antennas; wherein vertical projections of the first monopole antenna and the second monopole antenna onto a projection plane perpendicular to the bottom are interlaced.
