Abstract
The radiation characteristics of new microstrip electrically controllable traveling-wave antenna have been investigated, theoretically and experimentally. The substrate of this antenna consists of ceramic-polymer composite with modified ferroelectric powder Ba0,65Sr0,35TiO3 and appropriate polymer. The feasibility of dielectric scanning (changing the direction of the beam by varying the relative permittivity of the electrically controlled ceramic-polymer composite) has been investigated. It shows that the beam angle can easily change over 30° with varying DC bias field.
