my project title is Enhancement of DGS based UWB Antenna using Multilayer Metamaterial. I've done designing my UWB antenna and got the specification that i need. Metamaterial that i should design suppose to help increase the gain. Other than that, the metamaterial design should act a reflector to the antenna. So that it will help to increase the gain. But, i still stuck to design the metamaterial as the design i made still can't increase the gain of the antenna. Figure below shown how my antenna looks like and a few design that I've been tried before. If anyone know to solve this problem or tell which design could increase the value of the gain, it will be much helpful. Thank you.
Greetings, my suggestion would be to follow prof. Ganesh madhan's publications for the same,
Article A compact TRM antenna with high impedance surface for SAR re...
where professor would have discussed about how the unit element with nill phase variation at the band of resonance aids with degradation of back lobe radiation.
