PROBLEM TO BE SOLVED: To provide a cross dipole antenna unit whose number of components is small for easy assembling and which is light in weight. SOLUTION: A first dielectric substrate 110 and second dielectric substrate 120, with antenna elements of different shapes formed on both surfaces, are combined at a cut part. Engaging parts are inserted in engaging parts of a stage 130, where a grounding pattern 130a is formed on its surface so that the center axes of the first and second dielectric substrates coincide orthogonally with each other orthogonally. Under this condition, the cross dipole antenna mounted unit 100 is fixed to the stage. The antenna elements are so formed so as not to contact each other, a feed point and a shorting point are provided to the contact point between the end part of antenna element and the stage 130. With this configuration, a cross dipole antenna of high productivity and strength is provided. COPYRIGHT: (C)2009,JPO&INPIT
