Calculation of traveling-wave wire antenna arrays with mutual impedances
Abstract
An approximate method for computing the current distribution in a periodic waveguide antenna is presented. The current of an antenna element was corrected by taking into account coupling effects between adjacent elements. A 2 GHz grid antenna with low sidelobes is presented as an example.
