Talk:Antenna aperture

From Wikipedia, the free encyclopedia

Generally, antenna gain is increased by directing radiation in a single direction, while necessarily reducing it in all other directions since power cannot be created by the antenna. Thus the higher the gain, the larger the aperture and the narrower the beamwidth.

Does this mean the beamwidth will become narrower as a result of a larger aperture, or are beamwidth and aperture size independant variables that both affect gain? 121.45.235.106 12:34, 17 September 2007 (UTC)
