Field: Telecommunications (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. An antenna system comprising:
a phased array of elements spaced at a predetermined wavelength spacing, the phased array of elements being configured to generate an array element radiation pattern over a scan angle range; and
a reflector to reflect the array element radiation pattern from the phased array of elements to Earth, the reflector having a shape configured to establish a predetermined magnification as a function of the scan angle range so as to increase a field-of-view of the antenna system, wherein the shape of the reflector is further configured to adjust the array element radiation pattern, by increasing magnification relative to the scan angle range, to have a gain that increases with increases in scan angle relative to a boresight of the antenna system, wherein the reflector is configured to increase the scan angle range by a predetermined amount of degrees, and further wherein the shape of the reflector has a slope that is equal to half the predetermined amount of degrees for small scan angles,
wherein the phased array of elements is positioned at a feed location to receive radiation from the Earth reflected by the reflector.
