Base station antenna, feeder component and frame component

A feeder component for feeding a column of radiators configured to operate in a first polarization direction of a base station antenna, comprising:

• a stripline transmission line located rearward from a rear surface of a reflector of the base station antenna and substantially perpendicular to the reflector, wherein the stripline transmission line comprises:
• first and second ground plates that are parallel to each other, and
• a conductor strip that extends between the first and second ground plates, the conductor strip having an input part and a plurality of output parts,
• wherein the first and second ground plates are electrically connected to an outer conductor of a coaxial transmission line that feeds the column,
• wherein the input part is electrically connected to an inner conductor of the coaxial transmission line,
• wherein the plurality of output parts are configured to be electrically connected to the column to feed the column, and
• wherein the first and second ground plates are constructed as one piece with the reflector, so that the reflector is grounded via the first and second ground plates without a soldering connection therebetween.
