Abstract： |
The invention is concerned with moveable terminal antenna field. There are four plane monopoles printed on the surface of medium plant and at the four corners of it. The left and right antenna units and its feeding line are symmetrical arrangement about the longitudinal symmetrical axis of the medium plant, while the up and down antenna units keep away from each other in space in type of orthogonal manner. The metal ground relates the metal part to simulate other parts of the moveable parts, besides antenna, and all kinds of ground branch structure to reduce the coupling between antenna units or to adjust the work frequency of antenna units and the ground branch structure is symmetrical arrangement about the longitudinal symmetrical axis of the medium plant. It adopts plane print process with compact size and takes many measures to reduce the coupling of antenna units, increases the width of impedance tape and the plus of antenna and it can be applied into MIMO wireless communication system. |
