隨著無線通訊技術的不斷演進，人們所使用的行動裝置不斷地趨更輕、更小、且無線的方向改進。而為了使行動裝置的傳輸速度更快，現今普遍採用多輸入多輸出（MIMO）技術，即在同一裝端中配置多組天線，以同時發射與接收不同頻段的訊號。而這對天線間的隔離特性、極化方向及安裝位置皆具有嚴格要求。With the continuous evolution of wireless communication technology, mobile devices are becoming increasingly lighter, smaller, and wireless. To achieve faster transmission speeds, Multiple-Input Multiple-Output (MIMO) technology is now widely used, which involves configuring multiple antennas in the same device to simultaneously transmit and receive signals in different frequency bands. This places strict requirements on the isolation characteristics, polarization direction, and installation location of the antennas.
