摘要

提出了一种小尺寸印刷单极带耦合馈电多输入多输出(MIMO)天线,覆盖LTE700 (747-790 MHz)、GPS L1 (1485-1585 MHz)、IMT2100、WLAN和LTE2600频段。每个天线单元占用面积为120 × 60 mm2的大型移动电路板24 × 22.5 mm2的小体积。为了保持天线元件的小尺寸,选择弯曲线和端端与地平面短路的环路带。在接平面上增加一个槽和双倒l型接地支路,以减小天线单元之间的相互耦合。

Compact penta-band coupled-fed printed monopole MIMO/diversity antenna for smart mobile phone
A small size printed monopole with coupled-fed multiple input multiple output (MIMO) antenna is presented which covers the frequency bands LTE700 (747-790 MHz), GPS L1 (1485-1585 MHZ), IMT2100, WLAN, and LTE2600. Each antenna element occupies small volume i.e. 24 × 22.5 mm2 of large mobile circuit board of area 120 × 60 mm2. To maintain the small size of the antenna elements, meandered line and loop strip with end terminal short-circuited to the ground plane is chosen. A slot and a dual inverted L-shaped ground branch are added in the ground plane to decrease the mutual coupling between the antenna elements.
