Appeal No. 2001-1062
Application No. 08/910,297
Claim 1 is illustrative of the claimed invention, and it reads as follows:
1. A receiver for use with a first antenna which receives first polarized signals and a second
antenna which receives second polarized signals, the first polarized signals having a substantially
different polarization than the second polarized signals, said first polarized signals and said second
polarized signals being depolarized components of an original transmitted signal, the receiver
comprising:
a phase detector connected to the first antenna to receive the first polarized signal and to the
second antenna to receive the second polarized signal;
a phase shifter for adjusting the phase of the first polarized signal to produce a phase
compensated first signal; and
a combiner circuit connected to the second antenna to receive the second polarized signal
and to the phase shifter to receive the phase compensated first signal, the combiner circuit
constructively summing the second polarized signal and the phase compensated first signal to
generate a combined polarization received signal.
