The feed elements includes one or more inner feed elements and one or more outer feed elements.
The method further includes adjusting relative amplitudes of the inner feed elements and the outer feed elements to adjust the beamwidth of the antenna system.
An antenna system includes a reflector having a focal point, and a phased array having feed elements.
Each of the feed elements is disposed a same distance in wavelengths from the focal point, and is oriented towards the focal point.
The feed elements includes one or more inner feed elements and one or more outer feed elements.
The method further includes adjusting relative amplitudes of the inner feed elements and the outer feed elements to adjust the beamwidth of the antenna system.
An antenna system includes a reflector having a focal point, and a phased array having feed elements.
An adaptive antenna apparatus includes antenna elements (13,14).
