Flexible antenna is an essential part for the wireless sensor applications such as aerospace, communications, mobile communications, telemetry, medical, RFID etc., therefore, there is a huge interest in developing such antenna and in research on new materials with good electrical and mechanical properties to overcome limits of the traditional antenna and existing sensor systems. The desired frequency range in this work is the ISM (Industrial, Scientific, and Medical band), therefore, the patch

... ntennas were designed for 10 GHz. Ultrathin flexible glasses with thicknesses of 70 μm and 210 μm are used as substrate and Cu as metallization material. Cu with the lowest electrical resistivity after silver is a promising substitute for the aluminium. Glass is a suitable substrate material because of its low thermal expansion coefficient and the fact that it is resistant to most chemicals.
