MIMO ANTENNA AND MIMO ANTENNA SYSTEM CAPABLE OF IMPROVING ISOLATION CHARACTERISTIC

摘要

A MIMO antenna system and a MIMO antenna are provided to improve isolation characteristic and reduce mutual interference by placing both a radiation strip line and a radiator connected to a radiation plate symmetrically to a ground. A first radiator(20) and a second radiator(30) is located at one edge space of a ground(10), and the first radiator and the second radiator are formed in an opposite side perpendicular to the ground. The first radiator is comprised of a first radiation plate(21), a first radiation strip line(22), a first connector(23) and a first line connector(24). The second radiator is comprised of a second radiation plate(31), a second radiation strip line(32), a second connector(33) and a second line connector(34). The first radiation plate is parallelly arranged to a surface of the ground. The first radiation strip line is arranged in one side of the first radiation plate to form a certain gap from the first radiation plate. The first connector is located in the gap between the first radiation strip line and the first radiation plate to connect the first radiation plate and the first radiation strip line. The first radiation strip line is connected to one side of the edge of the ground through the first line connection part. The second radiator has the same structure as the first radiator.
