I have simulate a microstrip fractal antenna but the result is the vswr, and return loss still in narrow band, and the gain is too low as you can see it in the image, and i attach my project, if only someone can suggest some improvement
hiiii
I want to ask something
Do you design your Antenna to operates in 440 MHz and 800 MHz or the second frequency is the second harmonics of the first mode???
aslo you can widen the bandwidth by Using Finite Ground Plane
thanks
well i want to design it in 440 - 800 mhz range, since microstrip antenna only cover a narrow bandwith so i will make it resonance at this range, and what kind of finite ground plane, because i'm a newbie in this topic
