Re: Microwave Office
Hello Hasan Qasim,
The AWR MWO-EMSight is a shielded Mehtod of Moments (MoM) based Planar Electromagnetic Simulator and it is good for
Circuits such as Hybrid, MIC, MMIC PCB structures...
For using Antenna Analysis you need to take special care such as
1. To allow the antenna to radiate set the top boundary condition to Approx Open (which you did already)
2. Make sure the Antenna sits in the middle of the enclosure & doesn't near the walls of the enclosure
atleast far away 10 times the substrate layer Hieght (h)
3. THe Air layer above the dielectric substrate layer set to about 10Xh or 0.25 wavelength of the resonating frequency (fr)
Then you will get accurate results ...
For More details go through the online Help available in MWO...
MWO/AO/VSS User Guide -> Analysis Methods: Stability &Antenna -> Antenna Analysis Methods
Also if you want me to help on looking your antenna setup, upload the AWR MWO project file (*.emp) here or
send it to me
