A compact LTE antenna design for mobile device with full metal housing
A compact LTE antenna is proposed to work for mobile phone with full metal housing. Antenna miniaturization and electromagnetic decoupling to metal housing are realized by a high band only antenna structure, feed matching inductor and two tunable techniques. The final antenna size is only 60x8x7 mm3 and measured bandwidth can cover LTE frequencies from 700 960 and 1710 2170 MHz. The free space measured efficiency is about 45% and 60% at low and high band, respectively. This antenna showed great potential for real phone application under metal housing environment.
