i have refereed the so many papers in that they have used TM010 mode frequently so can you let know which mode i will select
Hello Raj Hakani, mode that u said TM010 is used to define the first resonance, so if u want to design/analyze your antenna, first you can design on that mode.

I am also agree with Dr Gunawan. If you can check it in first resonance using TM010.
@ Dr. Gunawan
i am agree with you answer but i am confuse because dominant mode for Patch antenna is TE10 so why they consider dominant mode TM010
Ok, i got it, we all know that the EM wave has it propagation on "x" axis and "y" axis, with "z" axis as a main direction on EM Wave, so TE100 and TM010 both are represent the first resonance of EM Wave inside the antenna.
I hope this can help :)
hello
usually for simple microstrip antenna the dominant mode is excited which include first mode. but for enhancing the performance of antenna you can excite other modes with proper techniques proportion with your application. for achieving the dimensions of microstrip antenna at specified frequency we refer to antenna book by balanis chapter 14.
best regards.
Dear Raj Hakani,
you can select TM010 mode, and this mode is used by almost all the design because it is the dominant mode of patch antenna in Transverse Magnetic,
and if you are considering transverse Electric than TE10 is the dominant mode.
[ nb: Dominant mode are the mode with lowest order resonant frequency] refer to Book Antenna Theory by Constantine A Balanis chapter 14, page 830

Only TM modes are generated between the patch and the ground. That is, transverse to the Z-axis of the antenna. Because, the magnetic fields in patch antennas are always transverse to their Z-axis. So, we consider E-field along Z-direction and MF along X and Y directions.
