This paper presents the modeling, simulations, fabrications and analysis of microstrip patch antenna & its feed lines. Microstrip antennas are of huge importance because of the advantages of their modest profile and less expensive printed circuit construction, and many forms have design and created for various applications. The characteristics parameters like dielectric constant (), thickness of the substrate (h) and antenna’s dominant-mode resonant frequency () is transformed into the patch dimensions that is length (l) and width (w) of the microstrip patch. The rectangular microstrip patch antenna with modified feed lines are designed & simulated for wireless communication application that works at 2.4 GHz. The microstrip feed line for microstrip patch antenna plays an important role to determine the return loss, gain & its radiation pattern. By modifying the microstrip feed line or inserting some discontinuities in it the return loss of the patch antennas could be reduced considerably, while gain and radiation performance is improved. In this paper a microstrip patch antenna is designed and simulated on FR4 substrate, with different feed lines using software’s based on MOM & FEM techniques. The microstrip patch antennas were fabricated on FR4 substrate with different feed lines S11(dB) were measured with Network analyzer. The work is of practical importance for microwave researchers and engineers.
