摘要：

A planar tri-band near-field resonant parasitic (NFRP) antenna for multiple-input multiple-output (MIMO) applications in the WLAN 2.4/5.2/5.8 GHz bands is presented. The tri-band functionality is obtained by introducing three different resonant parasitic elements near a simple driven element. Good impedance matching, radiation efficiency, and antenna patterns are realized at each of the desired resonant frequencies. Experimental confirmation of the simulated performance is presented. It is demonstrated that an array of these tri-band NFRP antennas obtains good isolation between elements even with small spacing between them. Calculated envelope correlation values are less than 0.12 within the bands of interest. The design methodologies of the tri-band NFRP antenna and the corresponding MIMO array are detailed.
