dimensions of Microstrip patch antenna

HI,
I am new to this forum. I would like to know about how the demensions of microstrip patch antenna can calculate?

you can look for a antenna book! It will discuss about this!

Thanks which book is better to study?

Book is a definite good suggestion. u can start with Antenna theory of Balanis or Antenna and wave propagation by R E Collins,

I suggest u first go through a video by antennatheory on Microstrip patch antenna design in youtube..! Give u a good reference to start with, den u can have better understanding from books..!
