Hello all

I want to cover frequency range of 500MHz to 5 Ghz, size of antenna should be as small as possible,

so which kind of antennas i can use for this kind of application and why?

Hope to get some quick and positive reply
 

thQs for your quick reply

i read come papers and according to them i got couple of more options
-micro strip patch antenna
-printed loop antenna

and you suggest micro strip spiral antenna

so i just wanna to know what are the positive and negative points of all these 3 antenna for this application
 

hi
microstrip spiral antenna have high bandwidth and with cavity back became directive and its drawback is hard to simulation and lower gain
