I think we refer to "beam antennas" that way because they behave like
lamps with reflectors, directing a beam of RF like a beam of light. I
don’t know the historical accuracy of my thinking.



I think from a historical perspective the name derives from 'Beam Stations'
such as those comprised in the Imperial Wireless Chain. That is stations
that were set up to 'beam' their signals to far flung places on the globe.

Antennas were not what would be described as beam antennas these days but
were types such as curtain arrays.

Surely the term "beam" is generic? I would have thought that any antenna
or antenna system which is deliberately designed to concentrate its
radiation or reception would qualify to be called thus.
