Abstract

This paper proposes a prototype of a flexible antenna which utilizes a star patch design. The work seeks feasibility of the star patch antenna to maintain its characteristic when it is bending on a curvy structure. The patch antenna is fabricated on a 0.8 mm thickness, h of polyimide film with a dielectric permittivity, εr of 3.4. The simulation result in Computer Simulation Technology Microwave Studio (CST MWS®) software shows that the antenna provides a -10 dB bandwidth of 24.9% at 2.45 GHz with a minimum reflection coefficient, S11 of -27.67 dB in the flat condition. The stability in its performance has been noticed in which the shift in the resonant frequency is less than 2% when the structure is bending on a curvy surface with a radius of 90 mm. The measured results in terms of reflection coefficient, bandwidth, radiation pattern and gain demonstrate a good agreement with the simulated results.
