摘要： An antenna comprises: a conductor plane; an island-shaped conductor group which is arranged to face the conductor plane with a dielectric medium therebetween; at least one power feeding part which is connected to one island-shaped conductor of the island-shaped conductor group and transmits power; and a connection part which electrically connects the conductor plane and a first island-shaped conductor that is an island-shaped conductor located on the outermost side of the island-shaped conductor group. Each of island-shaped conductors is capacitively connected to another island-shaped conductor adjacent thereto, the power feeding part is connected at a position other than the center of the island-shaped conductor in the arrangement direction of the island-shaped conductor group, and the connection part is connected at a position inside the first island-shaped conductor by approximately half the width of a second island-shaped conductor, which is an island-shaped conductor located adjacent to the first island-shaped conductor, in the arrangement direction of the island-shaped conductor group from a portion facing the second island-shaped conductor of the edge of the first island-shaped conductor.

摘要： A communication apparatus (1) includes a radio wave radiation source (10), a phase control plate (11) disposed near the radio wave radiation source, and a polarization control plate (12) disposed to be substantially parallel to the phase control plate (11). In the phase control plate (11), a phase of a transmitted electromagnetic wave differs according to a distance from a first representative point on the phase control plate (11). In the polarization control plate (12), 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 (12) to an edge of the polarization control plate (12), and a reference line connecting the second representative point to the reference point on the polarization control plate (12).
