本論文主要根據第四代行動通訊系統規範提出多輸出入平面偶極天線之設計,以得到高增益特性及良好的隔離度為主要設計考量,在平面偶極天線下方加入一圓形反射板及在三埠天線之間加入三角形立體柱以增強天線增益,且各單元天線之擺放方向相差120度以增加其隔離度。第一款天線應用於WiMAX系統,其阻抗頻寬為1762 / 850 MHz,涵蓋WiMAX系統之操作頻帶,實測峰值增益約為7.8 / 7.5 dBi,輻射效率大於80 %;第二款天線可操作於LTE系統頻帶,其阻抗頻寬為120 / 994 MHz,實測峰值增益約為4.8 / 7.4 dBi,輻射效率亦大於80 % 。此兩款天線皆具有高增益及良好隔離度之特性,相關參數探討將於本論文中提出說明與討論。
In this thesis, studies mainly focus on the multi-input/multi-output (MIMO) dipole antenna designs for fourth generation communication system. To achieve the requirements of high antenna gain and good isolation, a circular reflector is arranged below these element antennas with 120o of space difference, which have the triangle board between them. First, a novel planar MIMO dipole antenna with a pair of face-to-face U-shaped slots is proposed with the impedance bandwidths of 1762 / 850 MHz for the application of WiMAX system. The measured peak gains and radiation efficiencies are about 7.8 / 7.5 dBi and more than 80 %, respectively. Then, a novel planar MIMO dipole antenna with a shorted strip is proposed with the impedance bandwidths of 120 / 994 MHz for the LTE system. The measured peak gains are about 4.8 / 7.4 dBi with the radiation efficiencies also more than 80 %. Both of the proposed MIMO dipole antenna designs are described, and experimental results for the obtained high gain performance and uni-direction radiation patterns are presented and discussed.
