| Summary: | This paper presents the development of a flexible
antenna made of Polydimethylsiloxane (PDMS) and Copper (Cu)
patch. The antenna comprises of Cu tape as the patch and
ground plane, PDMS composite as the substrate and SMA
connector as the coaxial feed with dimensions of 21.5mm patch radius, 60x60x3 mm3 substrate area and 60x60 mm2 ground plane area. In this study, we also create a PDMS+glass microsphere composite as substitute to the PDMS substrate. The PDMS+glass inclusion reduces PDMS’s relative permittivity and loss tangent to 1.9 and 0.014 respectively which could enhance antenna’s
performance. To overcome adhesiveness issue between Cu patch
and PDMS substrate, the antenna was encapsulated with another
thin layer of PDMS/PDMS+glass substrate of 0.6mm thickness to
ensure a constant distance from the ground plane. CST software
was used to simulate antenna resonance frequency prior to the
fabrication. Measurements using a Vector Network Analyzer
(VNA) showed that the PDMS substrate antennas resonated at
1.92 GHz (without encapsulation) and 2.34 GHz (with
encapsulation) while the PDMS+glass substrate antennas
resonated at 2.46 GHz (without encapsulation) and 2.25 GHz
(with encapsulation) respectively. Here, we also discussed the
effect of substrate on return loss. Overall, results obtained from
the measurements are in agreement with the simulation results. |
