Development of microstrip patch antenna with change in materials and dimensions using MCM technology

The need to high frequency applications with small packaging require to use microstrip and printed antenna with developing technique to go forward with advanced technology today. Miniaturization usually comes at a price of reduced bandwidth, in this paper; the bandwidth enhancement techniques for microstrip antenna is presented with a major emphasis on the recent trends of minimization techniques such MCM (Multi chip Module) technology. For microstrip antenna there is tradeoff between high permittivity which increase directivity due to decrease return loss; leads to small sizes and between low permittivity with increase height of substrate to enhance bandwidth, hence optimum design used to get equilibrium between two points. The paper gives the results of minimization with change in dimensions and materials at range 1.22 GHz to 4.94GHz.
