PROBLEM TO BE SOLVED: To provide a transmitter capable of reducing deviation of the amplitude difference or deviation of the phase difference of signals radiated from a first antenna and a second antenna.SOLUTION: A transmitter has: a first antenna (108a) for performing wireless transmission of a first signal; a second antenna (108b) for performing wireless transmission of a second signal; phase control sections (104a, 104b) for controlling the phase so that the phases of the first and second signals are inverted from each other in a correction mode; first synthesis sections (112a-116a) for synthesizing the signals radiated from the first and second antennas; and amplitude control sections (105a, 105b) for controlling the amplitude so that the amplitude difference of the first and second signals is reduced, based on a signal synthesized by the first synthesis section.SELECTED DRAWING: Figure 1 |
