Summary:
This paper deals with the design and experimentation of ultra high frequency (UHF) planar inverted-F antenna in reduced size with patch geometry modification. The antenna which intended to operate around frequency of 920MHz for medical implant application is deployed on a 0.8mm thick of FR4 Epoxy dielectric substrate. Prior hardware realization, the parameters of antenna including reflection coefficient, gain, and radiation pattern as well as its physical dimension are investigated numerically to obtain the optimum performance design. From experimentation, it shows that the realized antenna which takes a rectangular spiral shape for its patch and has the total dimension of 15mm x 15mm resonates at frequency of 915MHz with gain and bandwidth of -27.03dBi and 17MHz, respectively.
