摘要

本文旨在设计一种在FCC波段(3- 11ghz)工作的微带天线，该天线具有较小的尺寸和超宽的带宽。为了增加带宽，使用了由原始矩形斑块的侧波纹组成的Koch分形。此外，为了提高匹配度，采用了锥钻，并将地平面形状由矩形改为半圆形。利用商业软件HFSS获得了回波损耗、增益、效率、辐射方向图和电流分布。对设计的天线进行了制作和测量，结果与HFSS仿真结果吻合较好。该天线的尺寸比在同一频段工作的其他微带天线要小。

Design and Analysis of Ultra-Wideband Koch Fractal Microstrip Patch Antenna

This paper is intended to design a microstrip antenna with reduced size and ultrawide bandwidth that operates in the FCC band (3-11 GHz). To increase the bandwidth, a Koch fractal was used that consists of side corrugations of the original rectangular patch. Furthermore, to improve the matching, a tapper has been used and the ground plane shape has been changed from rectangular to semicircular. The return loss, gain, efficiency, radiation pattern, and current distribution were obtained using the commercial software HFSS. The designed antenna was fabricated and measured with good agreement between HFSS simulations and measurements. The size of the proposed antenna was found to be smaller than other microstrip antennas operating in the same frequency band.
