Appeal No. 2006-0406
Application 09/497,865
BACKGROUND
The invention relates to a low profile tracking phased array
antenna for use on a commercial satellite terminal.
Claim 1 is reproduced below.
1. An antenna for communication with a satellite, the
antenna being for use on a satellite terminal, comprising:
a rotating plate for mechanically scanning for wave
signals in the azimuth direction;
a plurality of radiation elements positioned on said
rotating plate for electronically scanning for wave signals
in elevation, said radiation elements forming respective
element signals;
coding circuitry coupling a respective code to a
respective one of the element signals to form respective
coded element signals;
a multiplexer associated with said plurality of
radiation elements for consolidating the coded element
signals received at each of said plurality of radiation
elements to an analog bit stream;
an analog to digital converter for converting said
analog bit stream to a digital bit stream;
circuitry for forming multiple digital beams
corresponding to respective coded element signals from said
digital bit stream; and
a digital receiver determining signal strengths for the
coded element signals and locking onto a strongest signal
having a corresponding element, so that the corresponding
element can be used for transmission.
