| 英文摘要: |
| This paper presents three compact ultra-wideband (UWB) antennas fed by coplanar waveguide (CPW). The proposed antennas consist of a planar circular patch monopole UWB antenna and multiple etched slots on the feed line. Simulation by Ansoft high frequency structure simulator (HFSS) 10.0 shows that the in-band impedances are quite stable and satisfactory. Rejected narrow frequency bands are further obtained within the wideband width by inserting U-shaped slots into the fed line of the antennas. The antennas have a dimension of 50mm by 40mm by 1.5mm. The simulation and measurement results show that the proposed antennas have stable directional radiation patterns, very low profile and low fabrication cost, which are suitable for the UWB system. |
