本文介绍了两种透明导电薄膜制成的透明微带贴片天线，即多层薄膜（MLF; IZTO/Ag/IZTO）和金属网薄膜（MMF; Cu）。MLF和MMF的薄层电阻水平为2.52和0.18 Ω/平方。在550 nm波长处，MLF和MMF的吸收率分别超过80%和60%。天线的设计和尺寸遵循传统的简单微带贴片天线。一个透明的丙烯基片用于建议的透明天线。所提出的天线的导电部分也由铜片（CS;情况1）制成，用于与由MLF（情况2）和MMF（情况3）制成的两种类型的透明天线进行性能比较。对于Wi-Fi服务，天线的谐振频带为2.4-2.5 GHz。情况-1、情况-2和情况-3天线在Wi-Fi服务频带（2.45 GHz）的中心频率处分别具有4.75、-4.23和2.63 dB的峰值增益以及66.32%、7.76%和42.69%的辐射效率。
This letter presents transparent microstrip patch antennas made of two types of transparent conductive films, which are multilayer film (MLF; IZTO/Ag/IZTO) and metal-mesh film (MMF; Cu). The sheet resistance levels of the MLF and MMF are 2.52 and 0.18 Omega/square. The transparencies of the MLF and MMF are over 80% and 60% at a 550-nm wavelength, respectively. The design and dimensions of the antennas follow the conventional simple microstrip patch antenna. A transparent acryl substrate is used for the proposed transparent antennas. The conductive parts of the proposed antennas are also made of copper sheets (CS; case 1) for the performance comparison to two types of transparent antennas made of MLF (case 2) and MMF (case 3). The resonance frequency band of the antennas is 2.4-2.5 GHz for Wi-Fi service. The case-1, case-2, and case-3 antennas have peak gains of 4.75,-4.23, and 2.63 dB and have radiation efficiencies of 66.32%, 7.76%, and 42.69% at the center frequency of the Wi-Fi service band (2.45 GHz), respectively.
