Abstract

An antenna array comprising a main antenna for eight-band LTE/WWAN operation and an auxiliary antenna to combine with the main antenna for LTE MIMO operation in the mobile handset is presented. Both the main and auxiliary antennas are disposed at the bottom edge of the system circuit board of the handset and separated by a protruded ground. The main and auxiliary antennas can respectively fit in two small no-ground regions of 15 × 30 mm² and 15 × 20 mm² on the system circuit board, while the protruded ground in-between the two antennas has a width of 10 mm for mounting a USB data port. The main antenna covers the 704~960/1710~2690 MHz bands for eight-band LTE/WWAN operation, and the auxiliary antenna covers the 704~787/2300~2690 MHz bands such that the main and auxiliary antennas together can perform LTE MIMO operation in the LTE700/2300/2500 bands. The proposed antenna array is fabricated and tested. Results are presented and discussed.
