Speech Title: Prior Knowledge-Guided Deep Learning-enabled Generative Antenna Design

Abstract: Antenna technology has a rich history dating back to the 19th century, with continuous advancements aimed at meeting the escalating demands of wireless systems development. Over the past two decades, metamaterial-based antenna technologies have emerged as a significant avenue for enhancing various antenna parameters such as bandwidth, size reduction, gain enhancement, and mutual coupling suppression. Concurrently, the rapid evolution of artificial intelligence (AI), particularly generative neural network methodologies, presents a promising frontier in antenna design innovation.

This keynote speech explores the transformative potential of deep learning (DL), a subset of machine learning (ML) within AI, in revolutionizing antenna design. The presentation begins by outlining the prospective impact of DL on antenna innovation, followed by the introduction of two design exemplars employing generative adversarial networks (GANs). These examples illustrate novel approaches to metacell design within metasurfaces, achieved through pixelization techniques and DL-driven algorithms. Notably, the incorporation of prior knowledge (PK) in DL-enabled synthesis is elucidated, showcasing its efficacy in synthesizing metacells for metalens applications.

Furthermore, the presentation showcases how metalenses synthesized using PK-DL techniques exhibit breakthrough performance and offer additional functionalities in metalens antenna design. The discourse concludes by contemplating the future trajectory of Antenna+AI integration, highlighting its potential to redefine the boundaries of antenna engineering.
