Abstract

In this project presents the design of a round shape Kapton based flexible antenna that capable to operates at 3.5GHz (3.4GHz until 3.6GHz) frequency for 5G application. The circular shape patch antenna is proposed in this project by using Kapton substrate materials with relative permittivity of 3.5, thickness substrate is 0.025mm. Kapton is a great substrate as it produced good RF and thermal properties, it can developed at wide temperature range (-73 to +400°C), it is also high in resistant to many chemicals solvent in (Yang, 2017). Kapton is also known as Polyimide Film. Moreover, in (Dahalan et al., 2019) the Kapton is tend to be more flexible compare to other substrate. It can be applied to a direct antenna and depends on the frequency and application of the antenna. Kapton polyimide substrates was chosen for the design round shape flexible antenna. New technology needs that the antenna become lightweight, flexible and more suitable for digital applications whereby Kapton materials make an interesting substrates because of the fact that their miles are commonly used on the electronic industry as businesses shift to smaller, lighter and faster additives. The proposed antenna need to be simulated using the CST software to obtain and analyse the result.
