设计并模拟了在 4.76 GHz 频率下谐振的小型蝴蝶结天线。所提出的天线旨在检测和杀死导致癌症产生的肿瘤。自由空间中天线的带宽为 0.64 GHz。此外，在此条件下实现了-1.42 dB的增益和75.8%的高辐射效率。该天线体积较小，为34.46×23.8×1.67 mm3。选择厚度为1.6 mm的FR-4有损介电材料作为基板，因为它经济且易于采购。此外，还使用六层生物组织模型（包括肌肉层内半径为 10 毫米的肿瘤）来测试特定应用的天线性能。为了避免天线辐射的有害影响，天线放置在模型上，与其保持 2.5 mm 的距离。与未受伤组织相比，肿瘤中SAR值的增加证实了癌症的检测和治疗。
A miniaturized Bow-tie antenna that resonates at 4.76 GHz frequency is designed and simulated. The proposed antenna aims at detecting and killing tumor that is responsible for cancer generation. The bandwidth of the antenna is 0.64 GHz in free space. Moreover, a gain of −1.42 dB and a high radiation efficiency of 75.8% are achieved in such condition. The antenna has a small volume of 34.46 × 23.8 × 1.67 mm3. The FR-4 lossy dielectric material with 1.6 mm thickness is selected as the substrate because it is economical and procurable. In addition, a biological tissue model with six layers including a 10 mm radius tumor inside the muscle layer is used to test the antenna performance for specified applications. To avoid the harmful effects of antenna radiation, the antenna is placed on the phantom maintaining 2.5 mm distance from it. The detection and treatment of cancer are confirmed from the increased value of SAR in tumor compared to the uninjured tissues.
