Low-Band MIMO Antenna for Smartphones With Robust Performance to User Interaction

Abstract: This letter proposes a two-port MIMO smartphone antenna for frequency bands below 1 GHz, which is robust to user effects. The design is achieved by first analyzing the characteristic modes of a chassis that includes the large screen. Two modes predicted to be less affected by the user than other commonly used modes are selected. The modal currents and near-fields of the two desired modes then guide the design: The monopole-like mode introduced by the screen is tuned to resonance using shorting pins and selecti… Show more

“…The multiple-input multiple-output (MIMO) technology is a crucial part of improving the communication ability. It increases the channel capacity by increasing the number of transceiver antennas [5][6][7]. The combination of the two technologies can further improve the wireless communication systems, on the one hand in the communication band, on the other hand in the channel capacity.…”

“…multiple-input multiple-output (MIMO) technology came into being. This technology uses multiple antennas to transmit and receive without increasing spectrum resources and antenna power, which greatly improves communication quality [1][2][3][4][5][6][7]. New antennas require smaller and smaller sizes and more and more functions.…”
