摘要
提出了一种M型宽频带磁电偶极子天线结构,以传统磁电偶极子天线结构为基础,通过加载“A”型槽以增加高频谐振点并采用渐变型的阶梯状馈线进行馈电,可有效地展宽天线阻抗带宽。通过HFSS电磁仿真软件进行建模分析,可得:该天线相对带宽可达到73.9%(|S11|<-10 dB),能工作在5.54~12.03 GHz频带范围内,完全覆盖整个X波段,并且将天线增益提高至8.5 dBi左右。与传统天线相比具有结构较为简单,频带宽,增益稳定等优点,能够应用于X波段的通信系统中。
An M-type wide-band magneto-electric dipole antenna structure is proposed.Based on the traditional magneto-electric dipole antenna structure,the A-shaped groove is loaded to increase the high frequency resonance point,and the gradual step feeder is used for feeding,which can effectively widen the antenna impedance bandwidth.The modeling analysis with HFSS electromagnetic simulation software indicates that the antenna can reach 73.9%(|S11|<-10dB)in relative bandwidth,and work in the frequency range of 5.54~12.03GHz,completely covering the entire X-band,and the antenna gain is increased to about 8.5dBi.Compared with traditional antennas,it has the advantages of simple structure,wide frequency bandwidth and stable gain,and can be applied to X-band communication systems.
