Abstract

A small-size dual-antenna for the LTE operation in its high band of 1710~2690 MHz is presented for the LTE tablet computer application. The dual-antenna occupies a small volume of 10 × 45 × 0.8 mm³. The dual-antenna provides acceptable isolation better than about 10 dB and good antenna efficiency better than about 55% over a wide operating band of larger than 1 GHz. This leads to acceptable envelope correlation coefficient (less than 0.3 for the proposed dual-antenna) obtained for the LTE high-band operation. Results of the fabricated dual-antenna are presented, and the MIMO performance of the dual-antenna is discussed.
