Double Bazooka Antenna

Until recently, Base station antennas have been omnidirectional or sectored. This can be regarded as a waste of power as most of it will be radiated in other directions than toward the user. In addition, the power radiated in other directions will be experienced as interference by other...

FDTD method is a time domain analysis.Here we first we design a wave-guide and there after we just increase its broad side.Our aim is to this simulation is plotting its electric field response with time and how will it response in outside free space. Here we just take 170 time steps one who can...

This program is a very basic three-dimensonal FDTD program with a source in the middle of the problem space.This similar to the two dimensonal problem but here we assume that the source is not a point source. A simple Dipole Antenna consists of two arms where the current will flow and that causes...

This is an old program (1.999) that I have written for understanding radiation patterns of antennas. Basically I was looking for the relationship between interference diagram (Fourier transform of ilumination, usually called Array Factor) and 3D radiation pattern of the Array. For that reason, it...
