Metamaterials, with their extraordinary electromagnetic properties, have transformed antenna design by offering advanced control over signal propagation and radiation patterns. This review emphasizes on the integration techniques of major types of metamaterials in antennas to achieve significant gain enhancement. It begins with an overview of metamaterials, discussing their distinct types, properties, and the fundamental principles that enable them to manipulate electromagnetic waves in novel ways. The review then delves into the core topic: the application of these major types of metamaterials in enhancing antenna gain. It thoroughly examines four primary integration techniques, detailing the physical structures. Furthermore, the review analyses how specific metamaterials are integrated with different antennas along with their performances in terms of gain enhancement. Additionally, the review briefly addresses the current challenges and limitations in the existing techniques of integration of metamaterials with antennas in the context of recent advancements, emphasizing scopes for future research in order to fully exploit the potential of metamaterial-enhanced antennas.
