| 摘 要： | 多输入多输出(Multiple Input Multiple Output,MIMO)天线是MIMO技术的关键,现代无线通信领域的迅速发展对MIMO天线提出了许多新的要求.该文利用微带天线的低剖面特性,采用双线馈电的方式实现了两款双端口的MIMO天线,其中一款基于正方形辐射贴片,两个端口都工作于2.4GHz并且具有相同的辐射特性；改变贴片的尺寸可以得到另一款双频MIMO天线,分别工作于2.4GHz和3.5GHz,可以同时覆盖LTE(Long Term Evolution)、WiMAX(Worldwide Interoperability for Microwave Access)频段与WiFi(Wireless Fidelity)的部分频段,该天线的最大增益可达8dB,并且两个端口对应两个互相垂直的极化,满足室内基站的需要.

| Abstract: | MIMO (Multiple Input Multiple Output) antenna is a key component for the MIMO technique, and many
new requirements for MIMO antenna have been proposed by the rapid development of modern wireless communications. Two
dual-port MIMO antennas have been proposed in this paper, one of which based on the square radiating patch, both ports are
operating in the 2. 4GHz and having the same radiation characteristics. Another dual-band MIMO antenna can be obtained
by changing the patch size. The dual-band MIMO work at 2. 4GHz and 3. 5GHz respectively, which can cover LTE and
WiMAX bands as well as part bands of WiFi, the maximum gain of the antenna up to 8dB, and the two ports corresponding
to the two mutually perpendicular polarizations, these features can satisfy the needs of the indoor base station.refractivity |
