Study of a microstrip triangular patch antenna for body area network applications mounted on teflon cylindrical surface

Abstract

This paper proposes a novel class of conformal antenna having a triangular patch fabricated over a cylindrical surface for 4.78 GHz frequency application. Antenna is designed using Teflon in order to achieve the highest possible characteristics like gain and return loss with ease in conformal antenna designing. The motivation for this work was to devise a radiation element which has ability to conform to cylindrical shapes and for flexible BAN (Body area Network) and RFID applications. Also, this paper shows the advantage of triangular patch antenna as compared to rectangular patch design when fabricated on cylindrical substrate. We show that Teflon is not only cost efficient, as compare to other substrates, but also, shows good radiation characteristics with respect to simulated results and has tolerable limitations for operating temperature and excitation. Full wave approach is used to study designing equations for the radiating conformal patch. Finally, some numerical and graphical results are simulated and presented for the discussed application.
