Natural Optimization Algorithms in Synthesis Problems of Built-In Antennas of IoT Devices (Review)

摘要

Abstract This paper provides an overview of using natural algorithms of optimization for the synthesis of IoT built-in antennas that operate in frequency bands of data transmission protocols, such as GSM1800, GSM1900, UMTS, LTE2300, GSM + EGSM, Bluetooth, UNII-1 (5150–5250 MHz), UNII-2 (5250–5350 MHz), UNII-2 extended (5470–5725 MHz) and UNII-3 (5725–5825 MHz), WLAN 2.4–2.48 GHz, WiMAX 3.2–3.6 GHz, and WLAN 3.6 GHz. This review deals with the analysis of successful strategies of antenna synthesis for devices with built-in antennas. Such strategies include the principle of antenna geometry design, adjustment of optimization algorithms and building of goal function. The synthesis of IoT built-in antennas involves the use of genetic algorithm, particle swarm optimization algorithm, firefly algorithm and the simulated annealing algorithm.
