摘要

本文提出了一种高效、高增益的铅笔波束网格天线阵列,用于热疗乳腺癌治疗系统。提出的天线带宽从4.8 GHz扩展到4.9 GHz,谐振频率为4.86 GHz。该频段已被报道用于乳腺癌热疗。网格长边和短边分别负责不希望的交叉极化辐射和希望的共极化辐射。通过对传统栅格天线阵辐射特性的研究,证实了其不适用性。本文所提出的栅格天线阵列的短边宽度是可变的,长边宽度是尽可能宽的,以提高其辐射性能,减少损耗。此外,一个反射器已用于增益增强的目的。所提出的栅格天线阵列的旁瓣电平和3db波束宽度在e平面分别为-27.9 dB和25.9°,在h平面分别为-27.9 dB和26.3°。乳房假体分别被提议的和传统的栅格天线阵列照射10分钟。与传统的栅格天线阵列相比,所提出的栅格天线阵列在乳房幻像区域内实现了8°C的温度升高。所提出的栅格天线阵列具有高效率、高增益和重量轻的特点,具有非常适合热疗乳腺癌的辐射特性。

Pencil Beam Grid Antenna Array for Hyperthermia Breast Cancer Treatment System
In this paper, efficient, high gain and pencil beam grid antenna array is proposed for hyperthermia breast cancer therapy system. The proposed antenna bandwidth extends from 4.8 GHz to 4.9 GHz at resonant frequency of 4.86 GHz. This frequency band has been reported for the breast cancer hyperthermia therapy. The grid long and short sides are responsible for the undesired cross-polarized radiation and desired copolarized radiation, respectively. The unsuitability of the conventional grid antenna array is ensured by investigating its radiation properties. The proposed grid antenna array short side width is varied and its long side width is kept wide as possible to enhance the radiation properties and to reduce the losses. Also, a reflector has been used for gain enhancement purpose. The proposed grid antenna array achieves side lobe level and 3 dB beam width of —27.9 dB and 25.9° for the E-plane and —27.9 dB and 26.3° for the H-plane, respectively. The breast phantom is irradiated by both proposed and conventional grid antenna arrays for 10 minutes. The proposed grid antenna array achieves 8°C temperature increase within the breast phantom area compared to 2°C temperature increase for conventional one. The proposed grid antenna array is highly efficient, high gain and light weight, and it has a very suitable radiation property for hyperthermia breast cancer therapy.
