- Abstract:
- A simple and compact microstrip-fed ultra wideband(UWB)printed monopole antenna with band-notched performance is proposed for wireless universal serial-bus(WUSB). The antenna is composed of a U-shaped line radiator and a small strip bar and is partially grounded, so that the measured impedance bandwidth of the antenna is about 7.88 GHz covering 3.12 to 11 GHz with VSWR below 2, and the expected band rejection of 5.06 to 5.89 GHz is also obtained.The characteristics of the proposed antenna are analyzed, and the geometric parameters for optimal performance are investigated in detail.A relatively stable, quasi-omnidirectional and quasi-symmetrical radiation pattern is also found.The proposed band-notched UWB antenna requires no external filters to avoid interference with other systems, and thus, greatly simplifies the system design of an ultra wideband WUSB communication system.
- 给出了一种紧凑的可用于WUSB的新型带陷超宽带印刷单极子天线.天线由内嵌条带的U形环组成并采用部分接地技术, 从而使天线具有带陷超宽带特性.实测结果表明该天线输入端驻波比小于2的绝对阻抗带宽为7.88 GHz, 覆盖了3.12~11 GHz的频率范围, 其中5.06 ~5.89 GHz范围内具有带阻特性.讨论了各几何参数对天线性能的影响, 同时获得了该天线相对稳定的、近似全向且对称的测试方向图.由于此种天线无需额外的带阻滤波器来隔离天线与其他通信系统的干扰, 从而大大简化了WUSB系统的设计.
