Abstract (en)

[origin: WO0171847A1] A D net antenna is divided into two and one is provided, as a D net element (13), in an antenna element (1) while the other element is contained, as a lower element (10), in a cover section (2). An E net element (11) is connected to the upper end of the lower element (10). The E net element (11) has a rectangular radiation surface and thereby has substantial nondirectionality in the horizontal plane. The antenna element (1) is fixed removably to the cover section (2), so that the D net element (13) is connected with the lower element (10), thus providing a multi-frequency antenna operating over two wide frequency bands.
