Re: Need help my design before fabricate

Ivan...

Really sorry for the long post reply... really busy with fabrication... now the fabrication part almost done... thanks a lot for your help.. really appreciate it... Now, i need to analyze my radiation pattern for co-polar and cross-polar.. i hope you can figure me out for this case... here are how i find the graph using ansoft hfss..

Co-polar for E-plane:
category: Gain
quantity: GainTotal
function: dB
Theta: all values
Phi: 0 degree
Frequency: upper freq, center freq, lower freq

Co-polar for H-plane:
all same as above except for phi
Phi: 90 degree



Cross-polar for E-plane:
category: Gain
quantity: Gain3LX
function: dB
Theta: all values
Phi: 90 degree
Frequency: upper freq, center freq, lower freq

Cross-polar for H-plane:
same as above except for phi.
Phi: 0 degree

correct me if i done anything wrong
anyone who can help this out are also invited to help.. =D

Thanks a lot...

Sounds right. Now you gotta test ur antenna. Since we're talking about a broadband antenna, u can measure rad pattern with a vivaldi in anechoic chamber or an horn at the desired freq. To measure co an cross, just rotate the antenna used for the test of 90deg.
