DESIGN AND CHARACTERIZATION OF EDGE FED MICROSTRIP PATCH ANTENNAE

Abstract

Microstrip patch antenna has made great progress in recent years. Compared with conventional antennas, microstrip patch antennas have more advantages and better prospects. They are lighter in weight, low volume, low cost, low profile, smaller in dimension and ease of fabrication and conformity. Moreover, the microstrip patch antennas can provide circular polarization, dual frequency operation, frequency agility, broad band width, feeding flexibility, beam scanning unidirectional patterning. FECO tool was used for design and simulation, and each design was tuned to get the optimum value for gain and reflection coefficient. In this thesis work, a new approach of design and performance analysis of microstrip patch antenna. Performances of different feeding are compared with respect to gain, reflection coefficient and radiation pattern. In the design process of EDGE fed microstrip patch antenna with substrate material FR4 having specification such as relative dielectric constant Ԑr = 2.45, thickness h = 3.175 mm, metal conductivity = 5.88e7, conductor thickness T = 0.035 mm. After the simulation we got the simulated result reflection coefficient (S11) is -30dB, and VSWR is 1.022.
