HFSS15: Spherical Polar

Spherical Polar

The most fundamental description of the polarization state of a radiated field is spherical polar, which is the electric field phasor resolved in the directions of unit theta and phi vectors of the reference coordinate system. In this description, the field may be written as .

The polarization ratio for a predominantly f-polarized antenna is equal to

The polarization ratio for a predominantly q-polarized antenna is equal to
