S11 matching circuit stimualtion with ADS

[arr_baobao]

Hi guys

i have the antenna impedance s2p file from my network analyzer.
how do i design my matching circuit using ADS.
Anyone one got step by step guide ?

thanks.

Antenna is one port device.
Why do you have s2p ?

i mean s11 file looking out to the antenna from my transmitter.
how do i utilize this and do s11 matching on ADS.

thanks

I assume you have basic knowledge about RF enoughly.

Use the followings.

Then make conjugate matching.

BTW, answer my questions in the following.

the example only work on a single point frequency. what is i have a tx band of 200MHz bandwidth. I used the center frequency of the band and follow the step?

Wrong.

Use more matching components.

Can you understand Bode-Fano Criteria ?
