Design of TMLAA for the Utilization of Radiated Harmonic Beam Over Digital Modulation Schemes

ABSTRACT 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.
