Abstract :

Antennas have become increasingly vital across various domains, driven by advancements and a plethora of benefits they offer. Reconfigurable antennas, in particular, have found extensive application in personal healthcare, entertainment, military, and beyond. Their adaptability allows for superior performance compared to fixed antennas, as they can adjust parameters according to requirements.

In the realm of modern wireless applications, there's a growing need for antennas with integrated capabilities and functionalities. These include agility in resonant frequency spectrum, polarization, and radiation pattern diversity within a single device. Reconfigurable antennas emerge as a solution to meet such demands effectively. They offer versatility, allowing adjustments in frequency, pattern, or polarization, thus catering to diverse requirements.

In secure communications, antennas with reconfigurable radiation patterns are highly sought after. They play a crucial role in preventing signal information leakage, enhancing security measures. This paper aims to present an overview of existing antennas and their applications, with a focus on addressing limitations associated with wearable antennas. By understanding these aspects, it becomes possible to envision potential advancements in the field, paving the way for future innovations.
