【摘要】 本文提出了一种频率可重构天线可以在辐射方向大致不变的情况下(-38°和-39°),实现在频段8.55 GHz～8.78 GHz,14.77 GHz～16.48 GHz、16.58 GHz～17.30 GHz之间工作。提出了一种改进型谐振频率公式,通过加入等效修正因子ρ,等效修正常数η,扩展了谐振频率计算公式的适用范围。并根据热致天线变形的范围对改进型谐振频率公式进行了验证,以本文设计的3×3频率可重构天线为例,谐振频率计算最大误差不超过6%,满足工程要求,可以实现天线电性能的快速评估。更多还原

【Abstract】 In this paper,a frequency reconfigurable antenna is presented,which can be used with approximately constant radiation direction(-38°and-39°),It works between 8.55 GHz～8.78 GHz,14.77 GHz～16.48 GHz and 16.58 GHz～17.30 GHz.An improved formula for calculating the resonance frequency is presented.By adding an equivalent correction factor and an equivalent correction constant,the applicability of the formula for calculating the resonance frequency is extended.The improved resonant frequency formula is validated according to the range of thermal antenna distortion.Taking the frequency reconfigurable antenna designed in this paper as an example,the maximum error of resonant frequency calculation is not more than 6%,which meets the engineering requirements and can realize the rapid evaluation of antenna electrical performance.更多还原
