Hi everyone
I am designing a microstrip patch antenna (in HFSS). the return loss is good but its bandwdith is very small about 30MHz but i want to increase it to 200MHz and gain is about -4dB.
How can i increase bandwidth and gain..?
There is limitation on subistrate high and Er ( both must be kept constant to h=1.6mm and Er=4.7). and i can't change them..
