Experimental Characterization of Simulated PIFA Designed by Parametric Design Methodology

A verification of characterization of simulated PIFA designed by parametric design approach. The optimized dimensions derived from parametric simulation studies are considered for fabrication of real PIFA. Characterization parameters of the fabricated PIFA such as return loss (S11), VSWR, bandwidth (Δf), and impedance (Z) over the desired frequency band were measured. Vector Network Analyzer (VNA) was used to carry out the measured over the frequency range of 3 to 4 GHz. The antenna radiation characteristics were also obtained using anechoic chamber for E-filed and H-field measurements in same frequency range. The experimental and simulated PIFA characteristic parameters exited good agreement.
