Antenna

3D Array Factor of a 4x4 planar array antenna calculated using general formulas and then plotted in 3D format."AB" shows the excitation amplitude of the elements and "AB_phase" shows their phases.Elements are placed on the x and y axis and element factor is ignored. The code can easily be...

Transmission line length formula for coaxial cable to an antenna(the velocity factor for coax is approximately 0.66)frequency is in Mhz,length is in feet.

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...

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...

Communication signals can be attenuated at the receive antenna if there is a misalignment between the transmit and receive antenna. This can be either a static misalignment or a time varying misalignment, like when an antenna is mounted on a tower that sways in the wind.Communications signals can...
