how to choose multiple substrates of patch for maximum band width at 10GHz

[saikrishna011]

hi, first let me thank you for every one for good threads. its been very useful for my project

i have problem with increasing band width of patch
i am getting 800MHz at 10GHz(8% fractional BW) by E shape
i want to increase to 15 to 20 percent. is it possible
h=1.5,er=2.2
please suggest me how to choose multiple layers to increase BW.

THere may be considerable phase shift thru this wide dual bands and not possible.

I assume you have done something like this already https://goo.gl/z7bxP

The BW of a resonant patch antenna tends to increase with dielectric thickness.

Hello.
The bandwidth of microstrip patch can be increased by using of coupled resonators (patches):
-APERTURE COUPLED MICROSTRIP ANTENNAS;

-STACKED MICROSTRIP PATCH ANTENNAS https://www.edaboard.com/threads/214935/

you can simply increase the BW by working on ground plane also.
