I'm designing a hardware for a hobby purpose involving SIM900. I'm a newbie when it comes to antenna design. I was wondering what would be the best antenna choice to start with. Even though chip antennas do have some design complexities involves, I'm bend on using them since they're kind of compact. My question is whether chip antennas will be able to radiate enough power to transmit to cellular base stations. I haven't seen any SIM900 modules with chip antennas.
