Operating Band Height Area
GSM850/GSM900/DCS1800/PC
S1900
> 6 mm > 40 mm × 10 mm
For details about LTE antenna design, refer to the area requirement
of GSM antenna.
IFA antenna
IFA antenna shares similarity with Monopole antenna and PIFA antenna. IFA antenna has
two feeding branches, and allows ground under the antenna. The antenna has better
stability than Monopole antenna, and the antenna space requirement is between
Monopole antenna and PIFA antenna.
