摘要

In this article, a new configuration of a compact planar three-element multiple-input-multiple-output (MIMO) antenna system is proposed based on quasi-Yagi elements. A simple yet novel monopole driven three elements quasi-Yagi antenna (QYA) is designed to obtain a directional pattern over an ultra-wide bandwidth with a simple and compact configuration. The proposed single QYA contains the semi-elliptical driven monopole, the flared truncated ground plane reflector, a single elongated elliptical director and a simple microstrip feedline. The simulated and measured results showed that the proposed MIMO antenna system operates in an ultra-wide frequency range, starting from 1.53 to 6 GHz (118.7%, for |S_(11)| ＜ −10 dB), which covers several wireless communication bands. It has a compact total electrical area of 0.21λ_0~2 (λ_0 is the highest operating wavelength) and a minimum isolation of 17 dB between its ports with a common ground plane without any complex decoupling structure. For each element, the measured peak gain and simulated total efficiency variations are between 3.3-5.6 dBi and 77.6%-89%, respectively. There is good agreement between simulated and measured results. Furthermore, the calculated envelope correlation coefficient of ＜ 0.006, channel capacity loss of ＜ 0.2 bit/s/Hz, and stable total active reflection coefficient resonance are obtained over entire operating bandwidth, which conforms satisfactory MIMO/pattern diversity performance for wireless access-point applications.
