Abstract
A controller of a transmitter outputs cyclically different digital data to equivalent transmission circuits, that is, RF circuits to generate a rotation polarized wave.
Claims15
A transmitter comprising:
- a first transmission circuit and a second transmission circuit having at least one common circuit;
- and
- a controller which generates first digital data and outputs the first digital data to the first transmission circuit, and generates second digital data different from the first digital data and outputs the second digital data to the second transmission circuit, wherein outputs of the first transmission circuit and the second transmission circuit are transmitted from a pair of antennas spatially orthogonal to each other to generate a radio wave having a polarized wave rotating orthogonally to a propagation direction.
