Need help what measurement needed after fabrication done.

Dear All,

Need some advice and help regarding this matter.
What measurement needed and how to measure the results of the fabricated antenna whether it is working well same as the stimulation result?

thanks for taking time to answer my question.

Hai u should measure the "Return Loss-s11" value using Network Analyzer and it should be -10dB min ( or above than that) in ur operating frequency and check bandwidth. If it is working fine then u go for radiation pattern measurement in a anechoic chamber.

If i m doing Slot antenna design which able to work in 915 Mhz, do u have any suitable design which can provide -10dB min ? My design currently cant provide this output. Thanks
