how to use a network analyszer?

[kbmanick]

dear all,

how to measure ( GENERAL PROCEDURE) the return loss vs frequency for an single port antenna using a network analyzer? also the radiation pattern. plz give me the step by step procedure.


( N/W ANALYZER IS HAVING TWO PORTS. BUT ANTENNA IS HAVING ONLY ONE PORT. )


with thanks in advance,

kbmani

you could look it out in the catalog of the machine, I think .

Dear,

Take a look at manual.
In special in this points:
1- calibration
2- set frequency
3- format , s-parameters, smith chart, deg
4-save data, .s1p

It's very improtant for de-embedding when DUT is measurement. You need to remove the effect of the fixture.

1.first you need to calibrate the network analyzer with 1 port calibration.(open,short,load)
2. measure your antenna return loss(S11)
3. radiaton pattern needs extra instrument
