Dual band single feed patch antenna PCB design

Hello there, I'm new to AAC.

I'm working on an Iridium/GPS design and while trying to reduce components and size I found this antenna:


It's a dual band patch antenna with a single feed.

I'm not that experienced with RF and Antenna design and I wonder if I can use a singe patch antenna to feed both the Iridium system and the GPS system. If so, what are the considerations I need to have in order to have a successful design? At least impedance is the only thing that comes to my mind.

Thank you for your time and help.
