Introduction to Micro strip Patch Antenna Electronics Project:
In the late 1970 s micro strip antenna technology development began rapidly. In the early 1980s design and modeling micro strip antenna elements well established and workers turned their attentions to improving antenna performance features like bandwidth. One of the applications of new technology of integrated phased array systems used micro strip antennas. This micro strip antenna printed technology perfectly matched for high-density and low-cost integration with active MIC phase shifter and T/R circuit.
In the Massachusetts Antenna Lab University on August 1, 1984, Allen Buck, a graduate student fabricated 1st aperture coupled micro strip antenna. This antenna operated at 2 GHz and used a circular coupling aperture with 0.062” Duroid substrates. Most of the antennas developed using same process without any rigorous and designed CAD prototype and this first prototype had worked almost perfectly and had given the very good results on the radiation patterns and impedance matched.
In this most importantly we require small coupling aperture so that the back radiation level was much smaller than the forward radiation from the coupling aperture. Before 1970’s micro strip antenna concept was not developed. A micro strip antenna consists of dielectric substrate separated conducting patch on a ground plane. Many authors wrote articles, journals, essays on these developing methods of micro strip antenna technologies. Various mathematical models also developed on this antenna.
In designing a micro strip antenna its radiation patterns, Input impedance, length, Width and gain characteristics are considered and also various parameters considerations are discussed in this paper. While under operating conditions to send on board parameters to the ground Micros trip patch antenna used. The main aim of this paper is to design and fabricate a probe-fed square micro strip patch antenna and study of its required parameters like length, substrate thickness, relative dielectric constant, bandwidth and beam-width. In wireless applications micro strip patch antennas gaining popularity because of their small structure.
