Abstract

This paper presents a transmission line model used to design an inverted F antenna (IFA) at the frequency of 2.45 GHz. This model provides a quickly design of a printed F antenna antenna that can be easily integrated into handheld devices or printed on PCMCIA cards for WLAN communications in the ISM band. A simple iterative method which consider inductive or capacitive loadings was adopted to design the antenna in conjunction with a 3D EM simulators obtained a good solutions to design IFA. A prototype of proposed planar inverted F antenna (PIFA) has been manufactured on a FR4 substrate with a bandwidth of 230 MHz in order to demonstrate the reliability of the model validated by the good agreements with the experimental and simulated measurements.
