| 摘要 |
The present invention relates to multi-band antenna. This antenna comprises a substrate and at least one conductive layer provided with a plurality of antennas, such as PIFAs, resonating in specific frequency bands. The antennas are cascaded in order to achieve a compact antenna. The first antenna comprises a first radiating element (30), a first feed element (31 ) connected to said first radiating element and a first ground return element (32) and the second antennas comprises a second radiating element (20), a second feed element (21 ) connected to said second radiating element and a second ground return element (22). The ground plane (10) is printed in the same layer as the first or second antenna. |
