【摘要】 本文提出一种新型基于PCB板可应用于UWB系统的微带天线。该天线以1.6mm的FR4为衬底,采用双层板工艺。通过尺寸优化,所得天线面积为:30mm×35mm。使用基于Momentum电磁场仿真,结果表明,该天线在2．2-12 GHz全频段范围内回波损耗S11均小于-10dB,3-10GHz范围场强辐射极化圆图接近全向分布,满足 FCC的要求,可应用于3．1-10．6GHz的UWB无线通讯系统。更多还原

【Abstract】 A novel microstrip antenna for UWB system in the range of 3.1-10.6 GHz is proposed in this paper. The strip antenna is designed in the double-sided printed circuit board on a 1.6mm FR4 substrate. The whole area of this antenna is 30mmx35mm after optimization. The simulated results of the electromagnetic simulation based on Momentum show that all the values of return loss (S11) are less than -10dB in the whole frequency range of 2.2-12 GHz, and rough omni-directional characteristics are implemented. The proposed antenna can meet the standards set by FCC and can be adopted by UWB wireless communication system.更多还原
