Abstract

Adaptive control techniques are crucial in optimizing the performance of 2.45 GHz microwave transceivers amidst varying electrical parameters. These transceivers, integral to modern wireless communication systems, often encounter fluctuations in operating conditions that can impact signal quality and reliability. Adaptive control mechanisms enable real-time adjustment of transceiver parameters, ensuring consistent and efficient operation across diverse environments. This study addresses the adaptive control of a 2.45 GHz microwave transceiver in the presence of electrical parameter fluctuations, complemented by a multi-band antenna design aimed at minimizing losses. Electrical parameter fluctuations in transceivers can significantly affect performance and reliability, particularly in dynamic environments. The proposed approach integrates adaptive control algorithms to dynamically adjust transceiver parameters in response to fluctuations, ensuring optimal operational conditions. The integrated approach for adaptive control of a 2.45 GHz microwave transceiver, coupled with a multi-band antenna system optimized to reduce total harmonic distortion (THD). The study addresses the challenges posed by electrical parameter fluctuations in transceiver performance by employing adaptive control algorithms that dynamically adjust operational parameters. The multi-band antenna design, optimized through advanced modeling techniques, achieves a THD reduction of up to 20% across different frequency bands. Experimental validation demonstrates significant improvements in signal purity and transmission efficiency, showcasing the efficacy of this integrated approach in enhancing the reliability and performance of microwave communication systems in dynamic environments.
