how to understand equivalent circuit of any patch antenna

equivalent circuit of a patch

hi
can anyone plz help me
how to understand equivalent circuit of any conventional patch antenna?
I want to learn with basic, if possible.
is there any book and any documents that can help me to understand equivalent circuit ... ?
thanks

patch antenna equivalent circuit

Hello ayem9,

The best book to learn is " Microstrip Antenna Design Handbook" By Ramesh Garg, Prakash Bhartia, Inder Bahl, A. Ittipiboon

and the best article is
An accurate circuit model of a microstrip patch antenna for CAD applications
Kapsidis, D.; Chryssomallis, M.T.; Christodoulou, C.G.
Antennas and Propagation Society International Symposium, 2003. IEEE
Volume 3, Issue , 22-27 June 2003 Page(s): 120 - 123 vol.3

Summary: An equivalent circuit model, which takes into account the resonances of higher modes beyond the fundamental one, of a rectangular microstrip patch antenna is developed. The model is based on the broad-band transmission line model, and can be constructed to account for as many higher modes as it is desirable. Its good accuracy is proved after comparison with a full-wave analysis simulation program.

equivalent circuit microstrip patch antenna

thanx

Added after 8 minutes:

dear manju

thanx.
actually i need more in detail.
I want to know the physical insight for designing antenna with equivalent circuit
how can i get this book: Microstrip Antenna Design Handbook
can i get online or any link?
thanx again

I have the scanned version of the Handbook, but it is of a large size (~60M).

Dear Sir,

please shared that book on google drive .book name is Microstrip Antenna Design Handbook" By Ramesh Garg, Prakash Bhartia, Inder Bahl.
