The radiation module allows the computation and optimization of far and near field patterns of radiating circuits. The exited mode can be selected from the variety of all accessible modes at all ports. The field patterns are derived from the spherical wave coefficients of the radiating element at a fixed radius. A typical task for the µWave Wizard is the simultaneous optimization of the antenna pattern as well as of the transmission and reflection coefficients of complex networks.

BOR horn antenna elements

A set of elements has been developed which exploit the body of revolution symmetry of circular and coaxial waveguide horn antennas.  Although the new set of BOR elements is calculated with the same Mode-Matching (MM) method like before, those elements accelerate the computation for simultaneous analysis for fundamental and higher order modes excitations by subdivisions of the set of modes into de-coupled axial orders.
