Scattering Microwave Signal Analysis from Triangular Loop Element of Different Transparent Conductive Thin Films at Ku-band

A study on the performance of scattering ku-band microwave signals from an element designed with triangular loop shape made of different types of conductive thin film is presented in this paper. in this study, four types of transparent film have been used i.e. kapton, ito, aght-4 and aght-8. each of this film was then positioned on top of glass of solar panel which is based with rt/duroid 5880 substrate. the element was designed to be operated at ku-band frequency range. simulation results obtained from the cst microwave studio software showed that element of kapton film exhibits the best performance. the linear phase range reaches 361°, while the phase slope goes down as low as 0.063°/μm. it is also demonstrated that the dual frequency operational element contibutes the highest bandwidth of around 15.2% and also the best candidate to form a solar reflectarray antenna for terrestrial applications.
