In this work, a printed ultra-wideband (UWB) antenna has been proposed exhibiting band notch characteristics. The proposed design covers the entire UWB band except for the 3.5 GHz band providing the band notch for the WiMAX band. This design consists of two-quarter elliptical patches placed symmetrically over the FR4 substrate. The elliptical shape of the patch is responsible for the UWB band achieved. The slot has been created on the optimized patch area to achieve the desired characteristics providing a notch for the WiMAX band. The slot in the patch is so perfectly designed that it gives the patch a perfect shape of butterfly wings. After designing, the proposed antenna was simulated and then fabricated. The fabricated and simulated results are in close agreement with each other which shows, the proposed UWB antenna is good enough for biomedical applications.

在这项工作中，已经提出了一种印刷超宽带 (UWB) 天线，该天线具有带陷特性。提议的设计涵盖了整个 UWB 频段，除了 3.5 GHz 频段为 WiMAX 频段提供了频段陷波。该设计由对称放置在 FR4 基板上的四分之二椭圆贴片组成。贴片的椭圆形状是实现 UWB 频带的原因。该插槽已在优化的贴片区域上创建，以实现为 WiMAX 频段提供缺口的所需特性。贴片中的插槽设计得非常完美，使贴片具有完美的蝴蝶翅膀形状。设计完成后，对所提出的天线进行仿真，然后进行制造。捏造的结果和模拟的结果相互吻合，这表明，
