摘要： An antenna including a dipole antenna element having central feeding points, a common mode rejection filter, a first length of a two-conductor transmission line, and a common mode rejection filter arranged and connected between a far end of the first length of the two-conductor transmission line and the feeding points of the dipole antenna element. The first length of the two-conductor transmission line is arranged to extend from a ground plane to a first height where the first length of the two-conductor transmission line is connected to the common mode rejection filter.
