摘要

本文详细分析了一种新型圆形分形天线。天线安装在尺寸为48 x 60 mm2的FR4介电基板上。用50欧姆微带馈线激励天线。为了实现更宽的带宽，在地面上刻蚀一个槽。对于每一次迭代，都要调整槽的尺寸以达到预期的效果。在本文的后面部分，在微带馈线中插入U形槽，导致1.72 GHz (5.869 GHz—4.149 GHz)的有效带抑制。该天线具有稳定的辐射方向图和良好的回波损耗特性。所有的分析都是在HFSS 2013中完成的。

A Novel Circular Fractal Antenna with Band Notch Characteristics for UWB Applicatons

In this paper, a novel circular fractal antenna is analyzed in details. The antenna is mounted on a FR4 dielectric substrate having a dimension of 48 x 60 mm2. A 50 ohm microstrip feed line is used to excite the antenna. In order to realize wide bandwidth, a slot is etched in the ground. For each and every iteration, the slot dimension is adjusted in order to achieve desired results. In the later section of the paper, a U shaped slot is inserted in the microstrip feed line which leads to an effective band rejection of 1.72 GHz (5.869 GHz -- 4.149 GHz). The antenna shows stable radiation patterns and good return loss characteristics. All the analysis is done in HFSS 2013.
