Hello all,
I simulated circular polarized circular microstrip antenna in IE3D.
I am attaching .geo file can anybody tell how to measure beamwidth? Simulation frequency band- 2.25 GHz to 2.65 GHz
I am selecting Φ=0 and θ varying from 0 to 180....I am doing right?
I have manyfactured simple circular patch antenna for resonant frequency 2.45 GHz. But while testing it is showing that it is resonated at 2.48 GHz. Rest all parameters are as per specifications. I thnk problem will b in εr. i selected FR4 material and εr=4.4 for simulation.
Plz help regarding...
Generally feed point is on the axes. If u have cutted geometry then feed point may get shifted. If antenna is not perturbated then try feed point on x-axis.
Re: how to use IE3D
To johnson mike,
I m novice to IE3D. I used it for single layer circular micro strip antenna and i want to do two layer adding one more substrate above original one. how to do it? Can u help, Plz?
Send me resonant frequency. I'll let u know actual patch radius.
Added after 2 minutes:
Actually there is no such formula to determine actual radius. We have to solve for different values of a and chk out value of ae with calculated one. then we can decide a if match found. I have written...
In IE3D it is very easy.. Just click on probe feed to patch icon present in menu bar. Then window will pop up. In that window mention X and Y position of feed and no of segments ( generally eighteen), then specify the radius of feed probe.
Hope this will be useful to u.
Re: how is difference between HFSS software and IE3D softwa
Hello frnd,
HFSS is 3-D software, while IE3D is 2.5D simulation software. This much I know.
Hello all,
I know following formula
fr= Knm * C / 2* pi* ae* sqrt(er)
My question is if I want to fabricate antenna for 2.4 GHz then I'll get ae using above formula. But how to get actual patch radius a? Plz reply.
