I want to export a cst design to work in Microsoft Visio. I want to export a Yagi antenna design,which CST is detecting as mulilayer design. While I select to export in as a DXF file it only selects the element which is in xy plane. In my Yagi design as the driven element is in xy plane it is...
Inductor specification?
I need to buy very small size inductor which srf is above 3.2 GHz. When I buy a certain model of inductor, is the SRF mentioned in the datasheet of that inductor or I should measure it later after buying the inductor chip?
Re: Reconfigurable antenna isolating the bias from the RF signal?
thank you for your answer? you mean self resonant frequency of the inductor? why the srf above 3 GHz which is my upper limit of my antenna? I was searching for a reference while selecting the inductor? can you please suggest me a...
I am working on a pattern reconfigurable antenna and for this i need to bias the PIN diode from a battery through bias line. For this I need a RF choke inductance to isolate the ac from the bias line. I have seen different value of inductor is being used by different author. Is there any...
Hi normally we use PIN diodes for pattern reconfigurable antenna. My question is that as the current in antenna is ac how does the PIN diode works. Because diodes only let current flow only in one direction? When a pin diode is forward biased does it allow the ac current to flow in both direction?
HI I am designing a monopole antenna using cst. I need to use a infinite ground plane for better performance of the antenna. For infinite ground plane I have put Et=0 for boundaries where the ground plane is. But it is not giving me the result. I have heard a process of decoupling plane but I...
HI I am working on monopole antenna. But I experience one thing that when I increase the ground size to 3*lmbda or more i get total efficiency of the antenna greater than 100% which is not possible. When I decrease the ground plane size the efficiency is less than 100%. Can you please suggest me...
Thank you for your answer. I am actually working on a project and I need to calculate the signal strength from signal quality index. Can you please tell the definition of signal quality index and is there any equation that relates both? If you could suggest me any reference book it would be...
Hi I am confused about the concept of signal quality index. what is signal quality index? what is the relation between signal quality index and signal strength? can we determine signal strength from signal quality index?
Hi everyone. I am new person in antenna design sector. I need to optimize axial ration of an antenna with CST studio. can anyone let me know the process. that will be so much hlepful for me.
