Abstract
An antenna common to a plurality of frequencies in which a wide band of a UWB system can be covered while suppressing interference with other systems. The antenna comprises a plurality of element part conductors, coupling conductors for coupling them electrically, and a feeder for coupling one element part conductor electrically with a feeder part capable of feeding to that element part conductor, wherein respective element part conductors are concatenated sequentially by the coupling conductors. The element part conductor has a shape substantially symmetric to a line connecting the coupling conductors or the parts coupled with the feeder. Each coupling conductor is arranged substantially linearly and the plane part of each planar conductor is arranged substantially vertically.
