“…Compared with cylindrical DRA, rectangular DRA, and starshaped DRA, the bio-inspired spiral shell DRA demonstrated a wider bandwidth and higher gain. Another unique approach to achieving wideband operation has been reported in [11], which employs the growth pattern of a sneezewort plant with the Fibonacci sequence and golden ratio in branching and branch width respectively. The antenna prototype consists of a substrate sandwiched between a defective ground (defects or slots on the ground plane) and a plant-shaped patch.…”

“…For instance, the trunk typically branches into two main branches, then each of those branches further divides into two more branches, and so on, following to match the numbers in the Fibonacci sequence. Therefore, numerous design concepts have been proposed built upon this principle [10], [11]. Bio-inspired antenna designs offer several compelling advantages over traditional geometries, but their most striking feature is their significantly higher perimeter-to-area ratio.…”

This article presents an extensive examination of antennas rooted in nature and biology, showcasing their remarkable performance across a wide spectrum of frequencies-from microwave to terahertz. The limitations of traditional antenna design have become increasingly evident in the face of burgeoning demands for novel communication technologies. Conventional analytical-equation-based approaches struggle to deliver the combined performance characteristicsencompassing bandwidth, gain, radiation pattern, and miniaturizationthat emerging technologies necessitate. This has fueled an interest in bioinspired antenna designs, a paradigm shift drawing inspiration from the ingenious structural solutions found in the living and nonliving world, from plant leaves to bird feathers. These bio-inspired designs offer distinct advantages such as broader bandwidth and reduced sizes, making them highly appealing alternatives to the limitations of conventional antenna designs. This review explores a diverse range of bio-inspired designs. Among them are fractal geometries, inspired by self-repeating patterns in nature, which achieve optimal performance. Numerous designs in this category draw inspiration from nature, incorporating patterns observed in snowflakes, tree branches, clouds, and butterflies. Furthermore, nano-antennas have attracted significant attention for their vast potential applications in microwave and optical frequencies, playing a pivotal role in high-resolution spectroscopy, biomedical diagnosis and sensing, quantum photonics, and solar cell applications. By examining design methodologies and potential benefits, this article highlights the transformative potential of nature-inspired antennas. The compelling advantages of bio-inspired approaches necessitate a thorough exploration of their potential, paving the way for the development of next-generation communication systems with unprecedented capabilities.INDEX TERMS Bio-inspired antennas, Nano antennas, Wearable antennas, Fractal antennas.
