提出了一种用于无线局域网（WLAN）和全球微波接入互操作性（WiMAX）应用的紧凑型三频天线。所提出的天线印刷在FR 4基板上，总体尺寸为0.25.x0.29。在最低的频率。天线的阻抗带宽通过在贴片顶部引入槽来优化。接地平面是通过放置一个开口环谐振器阵列，以诱导额外的谐振，由于发生的磁偶极矩。该天线谐振频率为2.4GHz、3.5GHz和5.5GHz，带宽分别为12.5%、7.42%和6.36%，增益分别为2.25dBi、3.72dBi和2.71dBi，与实际制作结果吻合较好。该天线具有全向辐射方向图，适用于WLAN和WiMAX应用。
A compact tri-band antenna incorporated with a split ring resonator array is proposed for Wireless Local Area Network (WLAN) and Worldwide interoperability for microwave access (WiMAX) applications. The proposed antenna is printed on an FR4 substrate with overall dimensions of 0.25.x0.29. at the lowest frequency. Impedance bandwidth of the antenna is optimised by introducing slots on the top of the patch. The ground plane is engineered by placement of a split ring resonators array to induce additional resonance due to occurance of magnetic dipole moment. The antenna resonates at the frequencies of 2.4GHz, 3.5 GHz & 5.5GHz having bandwidths of 12.5%, 7.42% and 6.36% with the gains of 2.25 dBi, 3.72 dBi and 2.71 dBi, respectively which matches well with the fabricated results. The proposed antenna shows omnidirectional radiation pattern which makes it appropriate for WLAN and WiMAX applications.
