Bended rectangular patch antenna design for wearable applications.

In the past years, antennas have played crucial roles in the field of wireless devices for wearable applications. For designing the antenna according to its wearable applications, it needed to be bent. In this design, we used two different substrates for bending rectangular patch antennas, i.e., FR-4 epoxy and Teflon. By comparing the results obtained by both substrates, we prefer the effective one. An antenna with a Teflon substrate having dielectric constant 2.2 is considerable for the parametric analysis after the comparison with FR-4 epoxy for which, the dielectric constant is 4.4. The systematic study of the radiation pattern along with parametric analysis of the Teflon substrate of patch antenna for different bending angles has been carried out at operating frequency of 2.5 GHz. The design and simulation of the antenna that is bent on the E-plane is done using HFSS software. The final comparison of both the antennas makes designing of a bended antenna ease for antenna designers. [ABSTRACT FROM AUTHOR]
