hi, all
i have truble in define ports for simulation this loop antenna!
the antenna is placed on a FR4 board (it is not a microstrip! but a conductor wire placed on a dielectric board), point 1,2 are the feeding point conneted to a difference signal source ,so how to define the ports?
In CST your best bet ist to use the discrete port. Select the two points and then insert a discreter port with an impedance of 50ohm, or whatever you need, and you're away.
HFSS has something similar but i can't recall what they're called (lumped ports??)
I have tried useing a lumped port but i did't got the right answer,.
I thinks you didnot get the point of my question ,so i post the whole circuits here , please pay attension to the connection between the antenna and the chip!
please see my attachment below ,
thanks you guys anyway.
i am using CST with a multipin waveport to define the feeding line , i am trying to make the port to be a differential port. but i still can't get a promising solution.
anybody can help me ?
hi, JimLiu
I still get confused with the definition of lumped port
could you help me modify my CST modle ?
i attatched the file below!
thank you so much !
