Signal transmitting/receiving apparatus and method for controlling polarization

Disclosed are signal transmitting apparatus and method capable of generating polarizations that can be controlled in real time by allocating weights to signals. A signal transmitting method for generating variable polarizations having any vector through a plurality of radiating elements vertical to each other includes: receiving an input signal and separating the input signal into a plurality of separated signals according to the number of radiating elements; and allocating weights for controlling vectors of the variable polarizations to each of the plurality of separated signals, wherein the vectors of the variable polarizations are represented by a vector sum of the plurality of separated signals allocated with weights.
