【摘要】:為克服無線通信中系統(tǒng)間的相互干擾,基于天線頻段抑制技術(shù),設(shè)計一款具有雙阻帶特性的新型超寬帶單極子天線。采用加載、開槽等技術(shù),使其在2.6~14.6GHz頻帶內(nèi)回波損失小于-10dB。通過在接地板和輻射貼片上開槽,使其在IEEE802.16的3.3~3.6GHz、C波衛(wèi)星通信系統(tǒng)3.7~4.2GHz、IEEE802.11a的5.15~5.825GHz頻段內(nèi)駐波比大于2。仿真與測試結(jié)果表明,該天線具有良好的抑制功能,并且結(jié)構(gòu)簡單,體積小。
[Abstract]:In order to overcome the mutual interference between systems in wireless communication, a novel ultra-wideband monopole antenna with double bandgap characteristics is designed based on antenna band suppression technology. Using loading, slotting and other techniques, the echo loss in the 2.6~14.6GHz band is less than-10dB. The VSWR of IEEE 802.11a in the 5.15~5.825GHz band of IEEE 802.11a is greater than 2. 2. The VSWR of IEEE802.16, C-wave satellite communication system, IEEE 802.11a band and IEEE 802.11a band are 3.3GHz and 3.6GHz of IEEE 802.11a, 3.7GHz and 4.2GHz of C-wave satellite communication system, respectively. The simulation and test results show that the antenna has good suppression function, and the structure is simple and the size is small.
