Abstract
 

The demands of designing compact multi-band antennas to meet the growing requirements of integrating more wireless services in the narrow space of the mobile terminals are increased continuously. In order to meet this need, a multi-band multiple-input multiple-output (MIMO) antenna is proposed for various mobile terminals is this manuscript. The configuration of the antenna element of the 2×2 MIMO design consists of a multi-mode loop radiator with a pair of coupled parasitic structures placed at the upper edge of the smartphone printed circuit board (PCB). The loop antenna is a kind of self-balance antenna can operate at multi frequency bands. The employed substrate is a low-cost FR-4 laminate with an overall size of 75×150×1.6 mm3. Simple, compact and flexible structure of the antenna makes it easy to manufacture and installation. For S11≤−10 dB, the antenna elements of the MIMO design operate at the frequency ranges of 0.87–0.93 GHz, 1.7–1.8 GHz, 2.05–2.2 GHz, 3.5–6 GHz, and 6.7–7.3 GHz covering DCS, PCS, IMT, UMTS, LTE, and X operation bands. The designed MIMO antenna provides good efficiencies and sufficient gains in different frequency bands. In addition, the calculated TARC, ECC, and DG results of design are sufficient over the operation bands. The obtained results indicate that the proposed antenna can meet the actual demands of future smartphones.
