Shobit Agarwal

Hello Pranita,

As of now, there is NO book and/or article available in the market that can provide you exact calculation about the DGS and its effects. However, you may follow chapter 12 of the book "Microstrip and Printed Antenna" by Yahia MM Antar and Debatosh Guha. From there you will understand the basics of DGS.

Pranita Herwade

Thank you Mr. Shobit. I got the book online. I will definitely go through it.
