Understanding HFSS Coordinate System

Hi,

The angels at theoritical coordinate system are positive and between 0 to 360 degree, at HFSS the angles are between 0 to 180 degree and 0 to -180 degree, how can i see at HFSSDesign structure in negative angles ? i can not understand the relationship between Radiation Pattern Plot to the HFSSDesign structure .

Please advise.

Thanks

HI TXRX,

HFSS uses standard rectangular and spherical coordinate systems. See the help documentation in HFSS - there is a good writeup on spherical coordinates.
