sir i have an antenna with good result in hfss but is it possible predict if the antenna gives good mesurment befor the fabrication or we will not know that till we fabrication the antenna ? ( i dont want lost my money in fabrivation and finnaly the antenna doesnt work )
Hi i have 2 question to ask. 1. What connector type does the microstrip patch antenna usually use to connect to the VNA? Is it SMA Female? 2. How about to test coaxial type feed patch antenna? Have you tried testing it? Thank you. Love from Malaysia.
1. SMA female on patch since cable with VNA is generally SMA male. 2. These cables are different type of Coax with diff impedances, but generally VNA are 50 ohm, so that's why its either N type or SMA
aoa sir can you explain a bit some more? like what does it mean when the resonance is less than 10dB? and what does it mean if it's at 0? or maybe greater which isnt possible.
Zabardast for understanding how to use VNA and how to measure different parameters of Antenna
Hello,When we put the Antenna in Port1 or Port2?
great video dude, nice audio quality 🫶
Thanks for the crash course. Very pragmatic.
It was nice that you opened the video in the name of Allah.
Hello,When we put the Antenna in Port1 or Port2?
You can put it any port, but generally port 1 is preferable, due to default calibration

You will not know until you get the fabricated antenna,
Good explanation but I have powder form my samples how can I measure absorption properties of powder samples?

Very much helpful. Thank you sir

Less than -10 dB means that less than 10% of the signal is reflecting back
Where you put the Antenna? In port 1 or 2?
Port 1, but you can put it on either port, depends on your calibration
port 1 is the input of VNA ,we mesured S11 of Antenna without source?
How to measure gain antenna?
You need to use Anechoic Chamber, but I will eventually made a video where we can measure antenna gain using SDR
Assalamualaikum sir. Do you have video how to measure gain ?@@Muhammed_Mustaqim
our system support VNA autotest not just keysight but also R&S
My house probably cost what that vna did.

Hello,When we put the Antenna in Port1 or Port2?
You can put it on any port but use port 1 , so you can see S11, id you put it on port 2 then you look at S22, antenna is a single port device
