hi vijay,
for circular WG slots, try to extend the probe a little bit so tht when u apply the feed to tht face ,u wont face any prob..
the extension of the probe to be done based on the dimensionsof the circular WG.
for info u read extended probes in the articles..

thnk u.

hi,

i'm designing a cassegrain reflector antenna , initially i like to design the feed horn and the shaped subreflector in HFSS, but i don't know how to build the shaped reflector which is not exactly a hypeboliod but is a special shape defined by a equation.
so if anybody know the procedure to make it , kindly share it on this forum

with regards
abhi

U can go for HFSS designer. in which u can have a simple structure design of reflector antenna.......

try to adjust the parameters before u work in HFSS.

HFSS is very slow to simulate relatively complex antennas

only EM software provides you accurate results.
if you feel this is slow...then try out for Microstripes

hello sir;
I am dealing with hfssv9 i have some miss understand about models excitations using wave port , lumped port .... etc, i need some explanations about who those ports excite the models and what is the best choice of each model, also i want to design quad-ridged horn antenna for 10GH ,if u can post any data about this problems????
thank.
