For the 4th Generation (4G) of mobile communications the Long Term Evolution (LTE) standard requires the mobile terminals to operate in a significant amount of bands and a very wide range of frequencies. This is to say the handsets should be able to cover 24 different bands and all the frequencies from 700 MHz up to 2.7 GHz, which corresponds to the bands 12 and 7. Multi-band antennas have been largely used in the mobile phone industry in order to cover more than one band simultaneously. Their relatively easy-to-integrate structure and their low cost made them very attractive for antenna engineers.
