“…These designs demonstrate a potential to achieve wideband operation and improve overall antenna performance. Printed monopole antennas with UWB characteristics can be designed using petal shapes generated by applying the Gielis formula [6], [34]- [36], which involves polar transformation of structures like circles, squares, rectangles, or ellipses. An orchid petal-shaped printed monopole antenna was proposed for UWB indoor applications, targeting 4G and WLAN bands [31].…”

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.

This paper proposes a wideband coaxial line to rectangular waveguide transition to use in high-power microwave systems. The proposed structure consists of a supershape excitation probe in a rectangular waveguide. The structure's performance was measured and verified by fabricating a prototype. It was found that the measurement results are in good agreement with the simulation ones. The measured results indicate that the proposed structure's reflection coefficient and insertion loss are lower than -15 dB and 0.25 dB, respectively. Also, bandwidth increased from 7.8 to 15 GHz which is more than 63%. Therefore, the proposed transition can be utilized in different high-power microwave components and antenna applications.
