Abstract

The rapid development of wireless communication technology has driven the need for integrating multiple devices into a single platform to improve connectivity. Software-Defined Radio (SDR) stands out as a promising solution but requires antennas with an exceptionally wide bandwidth. This study introduces a super-wideband microstrip antenna designed to meet these needs, covering a frequency range of 0.42 to 40 GHz. The antenna is made using a Taconic TLY-5 substrate, known for its low dielectric loss, and has a simple printed monopole microstrip design with dimensions of 160 × 260 mm². Experimental results demonstrate that the antenna operates efficiently over a broad frequency range of 0.42 to 35.96 GHz, achieving a remarkable bandwidth ratio of 1:85. The antenna exhibits a gain exceeding 2 dBi across the entire frequency range, with a peak gain of 11 dBi, and maintains a total efficiency of over 60 % across this wide frequency spectrum. Its ability to achieve resonance at extremely low frequencies, combined with a remarkable 1:85 bandwidth ratio, significantly contributes to the novelty and impact of this work. This design demonstrates a practical and efficient solution for next-generation communication systems, combining wideband performance with compactness and ease of fabrication.

在软件无线电应用中具有宽频能力的改进椭圆型超宽带天线

无线通信技术的快速发展推动了将多个设备集成到单个平台以提高连接性的需求。软件定义无线电（SDR）作为一种很有前途的解决方案脱颖而出，但需要具有特别宽带宽的天线。本研究设计了一种超宽带微带天线来满足这些需求，覆盖频率范围为0.42至40 GHz。该天线采用Taconic TLY-5衬底，以其低介电损耗而闻名，并具有尺寸为160 × 260 mm²的简单印刷单极微带设计。实验结果表明，该天线在0.42 ~ 35.96 GHz的宽频率范围内工作效率高，带宽比达到1:85。该天线在整个频率范围内的增益超过2 dBi，峰值增益为11 dBi，并在此宽频谱内保持超过60%的总效率。它在极低频率下实现共振的能力，加上1:85的带宽比，极大地促进了这项工作的新颖性和影响力。本设计展示了下一代通信系统的实用和高效的解决方案，将宽带性能与紧凑和易于制造相结合。
