Hi all.
I need a suggestion. I have a aperture fed patch antenna with radiation plot as in figure below. It has a 5% bandwidth, and I can make it resonate as low as 300MHz up.
What do you think, what would be this antenna good for? It has low gain, but is small compared to normal square patch.
 

This antenna is small compared to normal square patch? How the size miniturization degree is achieved? and what is the substract you chosed?
 

It is a form of fractal antenna. I used FR4 for a substrate.
