Xnec2c is a high-performance multi-threaded electromagnetic simulation package to model antenna near- and far-field radiation patterns for Linux and UNIX operating systems.

Designed 1 X 2 Circular Patch Array antenna working at 2.4 GHz and having gain of 5.74 dB using HFSS (by ANSYS). Simulated the designed antenna & obtained it's 3D polar plot.

Antenna theory tools.

Rotary WARC Band (30, 17, 12m) dipole antenna. Constructed using alu tubes and utlizing common feed point method for all bands
