Optimized metamaterials for design of enhanced-performance high order mode dipole-driven Yagi-Uda antenna for millimeter wave applications

Abstract

This paper presents the development of a Yagi antenna optimized for third-order mode operation within the millimeter-wave (mmWave) spectrum. A third-order mode driven dipole, along with a reflector, is introduced to enhance the antenna's gain. The rigorous numerical optimization procedure was employed to precisely adjust the dimensions and positions of the driven dipole, director, and reflectors. The optimized Yagi antenna operates within the fifth generation (5G) band at 28 GHz, with a bandwidth of 2.6 GHz. Radiation pattern analysis indicates that the gain of the antenna in this higher resonant mode exceeds that of a conventional Yagi-Uda antenna, achieving a gain of 9.35 dBi at 28 GHz. To further increase the gain and address the path loss challenges in the mmWave spectrum, a near-zero index metamaterial (NZIM) array was integrated. A 5×5 unit cell array was embedded into the same antenna substrate, positioned in front of the reflector. The metamaterial array was optimized using the trust-region (TR) algorithm, resulting in a significant gain enhancement, reaching 13.8 dBi at 28 GHz while maintaining the operational bandwidth in terms of impedance matching. The antenna was subsequently fabricated and tested, with experimental results demonstrating a strong correlation with the simulated outcomes across all key parameters
