Applications for 1.3 GHz antenna

Hello guys,

I am working on an antenna which operates in 1.3GHz can anyone give some ideas about possible applications where this antenna can be useful.

What kind of antenna is it???

They are two. The first one is a spiral and the second one is a dipole which afterwards ends to a yagi. so finally i have three. I need general ideas of applications it is not necessary to be specific for each one but if you can specify them it is good for me.
Thanks hkprakash7
