Abstract
A communication apparatus () includes a radio wave radiation source (), a phase control plate () disposed near the radio wave radiation source, and a polarization control plate () disposed to be substantially parallel to the phase control plate (). In the phase control plate (), a phase of a transmitted electromagnetic wave differs according to a distance from a first representative point on the phase control plate (). In the polarization control plate (), a polarization state change given to a transmitted electromagnetic wave at a reference point differs according to an angle formed between a representative line connecting a second representative point on the polarization control plate () to an edge of the polarization control plate (), and a reference line connecting the second representative point to the reference point on the polarization control plate ().
