ABSTRACT:
Control of the directivity, reflectivity, transparency and tuning of R.F. antenna array is accomplished by building antenna with short dipole segments with a switch between each two segments. The elements are properly connected to exhibit these electrical characteristics by remotely controlling the closing and opening of selected switches. The means for controlling the switches is isolated from the R.F. working frequencies of the antenna.
