Design of Monopole Transparent Antenna for Satellite Internet Aboard Aircraft

This research presents the design of a transparent antenna for satellite internet aboard aircraft. The presented antenna comprises a triangular arrow monopole antenna fed by a tapered microstrip transmission line. It employs a polycarbonate composite substrate with a dielectric constant (εr) of 2.8 and a thickness (h) of 1 mm. The proposed transparent antenna achieves a bandwidth in the frequency range of 10.42–22.70 GHz, with an omnidirectional radiation pattern and an average gain of 2.57 dBi, effectively covering the Ku band for satellite internet applications. The antenna design was simulated using electromagnetic wave CST simulation software, and a prototype antenna was fabricated. The designed antenna exhibits a reflection coefficient of less than -10 dB throughout the 10.7–12.7 GHz frequency range, which is the operational frequency range for satellite internet and is an acceptable value in research terms. Moreover, a conductor with a thickness of 0.035 mm sits on a composite substrate material to form the antenna structure for satellite internet aboard aircraft. We need to study and apply various techniques to further enhance the antenna's performance in future designs.
