The method of researching the electrodynamic characteristics of the PAA radiating curtain described in this work applies to antennas with rectangular printed radiators and also other radiators that can be presented as an array of rectangular items. However, the charge method is applied to researching a printed vibrator radiator (fig.1) being part of an antenna array in this particular example...

The algorithm is based on representing the field on the source surface as an aggregate of the electrical and magnetic dipoles and reducting the vector problem to two scalar ones for the case of a point source. The results of calculating the directional diagrams and amplifying ratio are compared...
