using diode in antenna effect can increase leakage current ?

Please explain in details i have a doubt in this.

Thanks,

Of course attaching anything will increase leakage current.
The question is how much, enough to matter? Presumably
an antenna diode would be smaller or the same as a
minimum geometry FET's drain, and ungated so less leaky
than any of the transistors you use.

Diodes are meant to -prevent- antenna effect damage.
Antenna damage will cause way more leakage than the
diodes will, along with ruining reliability.

Thanks for giving this answer but i am not totally clear about your answer. i want to understand if i put diode for reducing antenna effect but putting that diode will cause leakage current then why should we do this? please give Little in deep ans..!!!!!!! and i thing antenna effect will not cause leakage current or is it ???

You have to get quantitative.

Every PN diode has reverse leakage. But you already
have a ton of them in your explicit circuit. They leak
too. Everything leaks when you get down to details.
"It leaks" is a meaningless statement. Like "There's
a molecule in my soup". Yes. And?

Every MOSFET S/D is also a PN diode, and almost
certainly bigger any gate output, sitting on the same
net. And most likely leakier because MOSFET channel
(especially in advanced nodes) leaks more than a
reverse biased diode of same W. Which the antenna
diode is likely less than.

Antenna damage either ruptures gate ox or, short of
that, does a lot of damage. That damage manifests
often as increased leakage either through the gate,
down the channel D-S, or both. Way more than the
antenna diode will leak. That's the value proposition.
