| Abstract: | A novel ultra-wide band omni-directional wire antenna was proposed. The crossed wire structure and small metal sphere were investigated to improve both the impedance bandwidth and radiation patterns. The proposed antenna was modeled and simulated in CST software. The results showed that the antenna can work well in 0.45GHz-28.4GHz, with VSWR less than 2; the radiation patterns of the proposed antenna keep stable within the whole band; out-of-roundness of the H plane is better than 5dB. The proposed antenna has important value in the field of electromagnetic environment monitoring. |
