An antenna in which a large antenna gain is obtained by having antenna directivity and a current leaking from a transmitting section to a receiving section can be blocked suitably. The antenna comprises a planar ground conductor plate, and two radiation conductors arranged side by side in parallel on the planar ground conductor plate in such a manner that they are symmetrical with each other with respect to the center of the planar ground conductor plate. Each radiation conductor is provided with a feeding port individually and operates independently. Isolation can be enhanced between the feeding points by bending the end part of each radiation conductor substantially perpendicularly to the planar ground plate in the direction having a maximum gain. ® KIPO & WIPO 2007
