Abstract
An antenna system comprises an antenna assembly having an angle of electrical tilt and a plurality of antenna elements each arranged to receive signals through a respective transmission line. Each transmission line is shortened or lengthened by moving a coupling link along two transmission line parts which the link couples: this adjusts signal phase supplied to each antenna element individually, and controls the angle of electrical tilt of the antenna assembly.
