摘要
本文提出了一种用于多信道通信的时调制线性天线阵列(TMLAA)的多谐波波束的有效控制方法。采用基于课堂学习的基于教学的优化方法(TLBO)对16元TMLAA进行谐波转向的主动持续时间优化。采用优化技术的仿真研究有效地引导了前两个谐波波束,增强了辐射功率和可观的旁瓣电平(SLL)低于-20 dB $,\ mathm {dB}$。此外,为了实际验证,在一个场景中给出了制造原型的测量。最后,通过测量所考虑的数字调制方案的误码率(BER)来验证谐波波束在通信链路中的使用。
Design of TMLAA for the Utilization of Radiated Harmonic Beam Over Digital Modulation Schemes
This work presents the effective steering of multi-harmonic beams of a time-modulated linear antenna array (TMLAA) for multi-channel communication. A classroom learning-inspired Teaching Learning Based Optimization (TLBO) is utilized for active duration optimization of the 16-element TMLAA for harmonic steering. The simulation study employing the optimization technique effectively steered the first two harmonic beams with enhanced radiated power and considerable Sidelobe level (SLL) below . Further, for practical validation, the measurement of the fabricated prototype is presented for one scenario. Finally, the use of harmonic beams for the communication links is validated by measuring the bit error rate (BER) of the considered digitally modulated scheme.
