生物医学用PET基片上1 × 4 CPW微带天线阵的设计
Design of a 1x4 CPW Microstrip Antenna Array on PET Substrate for Biomedical Applications
摘要：
本文提出了一种应用于生物医学的单层共面波导馈电微带贴片天线阵。所提出的天线阵列在透明和柔性的聚对苯二甲酸乙二醇酯基板上实现，具有1x4辐射元件，尺寸仅为280 x 192 mm2。天线阵列谐振频率为2.68 GHz，峰值模拟增益为10 dBi。还制造了原型，并且使用具有成本效益的粘合剂铜箔而不是传统的铜或银纳米粒子墨水绘制导电图案。相应的测量结果与模拟结果吻合较好。所提出的低轮廓和具有成本效益的发射天线阵列具有用于可穿戴的穿戴式应用的潜力，包括可植入医疗设备的无线供电。
英文摘要：
In this paper, a single layer Coplanar Waveguide-fed microstrip patch antenna array is presented for biomedical applications. The proposed antenna array is realized on a transparent and flexible Polyethylene Terephthalate substrate, has 1x4 radiating elements and measures only 280 x 192 mm2. The antenna array resonates at 2.68 GHz and has a peak-simulated gain of 10 dBi. A prototype is also fabricated, and the conductive patterns are drawn using cost-efficient adhesive copper foils instead of conventional copper or silver nanoparticle ink. The corresponding measured results agree well with the simulated results. The proposed low profile and cost-efficient transmit antenna array has the potential for wearable born-worn applications, including wireless powering of implantable medical devices.
