Analysis and Computation of different parameters of High Frequency Antennas

This paper concentrates in the Analysis and Computation of parameters of High Frequency Antennas e.g. Far field, Standing Wave Ratio, Reflection coefficient, Total Gain, Front to Back Ratio (FBR) etc. by using Numerical Electromagnetic Code (4NEC2) software. The Extended Version of the software i.e. 4NEC2X was used, because Real Time 3D Viewing is not enabled in 4NEC2. The radiation pattern is the graphical depletion of the relative field strength transmitted from or received by the antenna as a function of Space Coordinate. As such, antennas radiate several curve which are crucial in describing the respective antennas. Consequently, our analysis reveals that, antennas show very good characteristics at the operating frequencies compared to any other frequencies.
